The recording timestamp problem is an easy fix, too. The text says it's telling you the creation time, but it actually reports the modification time, i.e. when the recording finished. It would be simple to fix it to read the other field and report when the recording started, but apparently we're not getting any more firmware updates. Perhaps they don't want to incur more anger by again neglecting CC support in 2.1.1.

Ok, this makes sense now. I did have those two ION channel on the GoTo list, and I removed them now. My previous message saying it shutdown itself while I was watching a replay of a program, and at the same time there was a background recording on-going. So it seems to be the same problem then. I didn't know that it does a channel sweeping at the beginning of the TV mode, and I didn't have this problem for 2 1/2 months but that could be some new changes from those stations. thanks.

Mine still shut off even after deleting the 3 ION stations, and it crashed when I did not even go into the HDTV portion of the TVIX. I was in Movie mode and when I hit setup it shut off. That is when mine seems to shut down, when I hit the setup button. Does not do it often but it still does it. I might pull the HD out and test it for awhile just to see if it does not like the HD installed.....

You can control the output. Page 20.

These are estimates based on 1080i cable doing a manual recording.

One episode I recorded last week was 4.9 GiB, and the next week's episode was 7.8 GiB. Apparently the station manager tweaked some settings over the weekend, or something. If your HDD gets full, the TViX will let you just switch it out for an empty one, or you can transfer files from the TViX HDD to an external one via USB or LAN.



Thanks guys, I appreciate the detailed replys to my question.

One other thing...

Does anyone here have a concern/fear over the lack of COMPONENT VIDEO OUTPUTS??? (analog "hole" technology)

Kinda wondering if the broadcast content providers will figure out a way to block/restrict/frustrate the small group of us trying to archive our favorite shows again.

I've been burned before with their clever slight of hand techniques...

A few years ago, I purchased a very expensive digital video recording setup, that was setup specifically to record high-definition television shows & sporting events. (not a severely watered down SDTV or down-converted HDTV version)

I was using the IEEE 1394 Firewire input on a JVC D-VHS recorder ($$$$$) to capture the raw bitsream from a satellite set top box. Well, as some of you may already know, the content providers were not exactly thrilled about this "creative" method of recording their raw HDTV bitstream signal...so they embedded a broadcast flag into the actual bitstream that rendered my 1394 Firewire input totally useless. This digital bitstream signal manipulation effectively shut off access to the HDTV content I was trying to record. (full spectrum 1080i & 720p HDTV programming)

I was obviously bummed out, once I realized I had been effectively back-doored by the broadcasters in this regard.

So I said all that, to say this....

Does anyone here (who got the shaft before), fear that history will repeat itself? (because of the 'digital handshake' dependent HDMI 1.3 HDTV output)

As I understand it, the HDMI 1.3 digital video connection is standardized throughout the video industry. (regardless of the set-top box in question)

I wonder if they could somehow block the digital video OUTPUT(playback), in the same manner they blocked the digital video INPUT on my JVC D-VHS HDTV recorder? I never saw that bullet coming, until it hit me right between the eyes...

Please let me know if I'm just being too paranoid here. (and why)

I have the JVC and Mitsubishi D-VHS recorders.

Beyond that I have nothing to contribute, sorry.

It's true that HDMI supports DRM garbage, but to my knowledge, the TViX doesn't use any of it. That's apparently one reason why the TViX isn't DLNA certified: DLNA-compatible devices must adopt certain DRM schemes, and the TViX employs no copy protection. If the broadcasters did start trying to manipulate the MPEG-2 TS to prevent copying, it would also probably break DVRs like the CM 7400, TViX, and perhaps even TiVo. You can only do so much to "secure" broadcast content, and the really evil DRM schemes are forbidden by the FCC for broadcast content (AFAIK), since they wouldn't be compatible with the tuners in all standard ATSC TV sets.

Now, even if stations did somehow come up with a way to prevent you from copying shows with the TViX HDMI output, it doesn't matter. You can just use the USB or LAN functionality to transfer the files off the TViX to a computer. Unlike the CM 7400, recordings aren't "locked" to the HDD of the TViX. You can transfer them to another machine or even swap the TViX HDD into a regular computer to alter its contents. The TViX uses a standard NTFS partition with the unencrypted TS sent by the station you recorded, and there's PC software for manipulating that format.

I'm not a huge fan of HDMI either, but since the TViX is a foreign-made DVR that apparently doesn't utilize the DRM available over HDMI, there's nothing to worry about. Considering the gaping security hole created by letting you access the TViX HDD over USB and LAN, there wouldn't be any point in using HDMI DRM, anyway.
post #1477 of 2239
One clarification: The Firewire encryption scheme, aka "5C" has nothing directly to do with the "broadcast flag" or HDMI. The BF is part of the ATSC spec. and was, at least temporarily, shot down by the FCC so that we may continue to view DTV without a decoder box on top of the set. 5C is built into the IEEE-1394 spec. and has been alive and well on Firewire since day one.

The cable companies and their content providers are not bound by the same FCC rules against encrypting content as are OTA stations. Technically, only the latter are "broadcasters" while the former are allowed to "protect" their stuff so that only valid subscribers may access it--and with 5C encryption, there are several levels of permitted access, ranging from no copying to infinite copying.
post #1478 of 2239
TPeterson comes to the rescue with the actual names of the protection schemes!

It would be pretty silly if broadcasters were able to set flags on their content that would require you to have a STB to watch the stations. If you needed to rent a STB to watch OTA TV, what would be the point of it anymore? It would be the same model as other pay-TV services. I'm surprised the FCC allows the ION stations to do the AirBox thing, but I'm guessing that ION couldn't do it anymore if they discontinued their three unencrypted channels.

As TPeterson said, the encryption used by pay-TV services is what requires you to have a STB to watch any of the channels (and a CableCard to record them), since standard tuners can't decrypt them.

Regarding the ATSC BF flag, I wonder if the TViX respects it. It's a little disconcerting to know that stations have the ability to mark content as un-recordable. If the subscription-free DVR solutions respect the BF and stations are ever permitted to use it, perhaps VCRs and other analogue recording options will again have a use...
post #1479 of 2239
Thanks guys!

TPeterson,

I appreciate the technical breakdown of the issue. I knew the details back then, but it's been 4+ years since I abandoned the whole IEEE 1394 Firewire DVHS recording path, and I must admit I completely forgot the 5C encryption was primarily setup to restrict access to the raw data stream for content on the PAY CABLE channels like ESPN, HBO, & SHOWTIME.

Thanks for refreshing my memory about what which HDTV content was scrambled...and what was not.

I am considering the 6620N, for it's ability to record and archive free HDTV OTA content ONLY...so I guess for now, an out-of-left-field copy protection scheme wouldn't be a pressing concern in that case.

I've read that since the entire broadcast frequency spectrum is technically "OWNED" by the U.S. government (but LEASED to the OTA broadcasters like ABC, CBS, NBC, FOX, & PBS), and they must abide by their wishes to keep all their broadcast content free and unscrambled at all times. (enforced by the FCC)

I'm guessing it would take a federal court challenge (by those particular OTA networks), to actually circumvent the existing federal laws.

With that fear alleviated, it looks like a 6620N would be the perfect device for my specific needs right now.
post #1480 of 2239
I experienced what I assume is my first software glitch this evening. I loaded a recording from last night and tried to skip forward through the start padding to the beginning of the show, and nothing seemed to happen. I tried again, and I saw the jump value on the screen as "0" seconds, which explained the lack of results. I went into the options and found that both the forward and backward jump values for video and time shifting had changed to 0. I fixed the values and reloaded my recording, and the jump function worked normally again. I don't recall seeing anyone else post about such an experience, but I thought I'd mention it. Hopefully it's not indicative of a more serious problem. The unit started normally a few hours later to do its scheduled recording, at any rate.

I've also seen this happen once. I've no idea what was the cause.
post #1482 of 2239
Mine did that last weekend as well. It has done it several times in the past. It also reset the channel used to set the clock (got set back to "Any Channel"), so I wonder what other parameters get reset as well.

I filed a bug report with DVICO earlier this week, but they've taken to ignoring my postings.
post #1483 of 2239
+1 to the list of "0" seconds jump value. Also, for me, any forward jump value of 100 seconds or more would result in unpredictable forward jump times.
post #1484 of 2239
I've complained about losing the jump settings. It's related to the unexpected shutdowns (like an ION station crash, etc.).

Also I've found can force a shutdown without saving by pressing the on/off button when the TViX says "saving" during a regular shutdown. It will shutdown without saving (so you'll lose any scheduled recording changes for sure). And you'll take the chance that the jump settings are reset to zero.
post #1485 of 2239
I've also noticed that the saving message before the system shuts down is sometimes displayed at half the front panel's normal brightness, but I can't find any specific cause for that behaviour, either.
post #1486 of 2239
Question:

Is everyone who is experiencing these 'jump' issues, using the most current OS software update from DVICO?

If so...

Did anyone notice the same issues with any of the previous software OS updates? Or is this a relatively NEW issue that has never been seen before?
post #1487 of 2239
Sean, it's been so long since I've seen the issue that I'm not sure if it happened with the latest firmware or not. Anyway, I doubt that it's a "new" issue. As doranu suggested, it may be related to ION-type shutdowns, and if so that would be a good reason for me not to have seen it lately, as I've deleted the ION stations from the GoTo menu.
post #1488 of 2239
I know it happens with 2.1.0, as that's the only firmware I've used. I also deleted the ION channels after doing the initial channel scan, so I've never had a sudden shutdown on my unit (yet, knock on wood...).

Thanks.

I'll likely do the same, as I rarely watch anything on the ION channels anyway.

On a separate note...

Which current 1TB-2TB HDD would you guys consider buying NOW, to install inside the TVIX M6620-N? (latest and the greatest)

I'm going to order something soon, so I figured that I would ask you guys what has been working (reliably) for you thus far? Just trying to find the best reasonably priced HDD model I can buy. (that won't let me down)

Would anyone go so far as to say, that there is a CONSENSUS pick for the best HDD in this particular application? (continuous digital video recording/playback duty)

Western Digital? Seagate? Samsung?

Please post any specific hard drive models you would recommend that fit that description.

Any 'virtual locks' (or slam dunks)...would be greatly appreciated.

I have a short list of hard drives that I want to use, but I'd like to get some real-world feedback from the guys currently using this PVR first. (and your overall impressions of their performance/durability over time)

I'm trying to avoid an obvious mistake here.

I want to purchase a stable 1-2 TB hard drive, that has very good reliability and performance characteristics. More importantly, I want to avoid any inherently poor hard disk drives that have displayed short-term (or longterm) reliability issues in these TVIX PVR's. (with regards to this intense data-writing/re-writing application)

I'd like to hear about any HDD models that have repeatedly and constantly died a pre-mature death in this unit.

and...

Any HDD's that have experienced serious recording/playback issues due to internal overheating, or drives that will not format properly for use in the M6620-N.

TIA
post #1490 of 2239
@ Sean

I was in the same situation as you just a few weeks ago. I came to the conclusion that there is no current HDD that meets those criteria, as I was also looking for a 1-2TB drive that would work well in a DVR application.

The main limiting factor on disks suited for DVR installation is that heat and power ratings are more important than speed. Since a DVR will be reading and writing huge amounts of data at a relatively slow rate (~20Mbps), having a high-speed HDD isn't necessary, while having a cool-running one is. Most HDDs on the market are 7200+ RPM (because old HDD technology is trying to compete with the new SSD technology on speed), and a DVR runs cooler and more reliably with a 5400 RPM drive. That speed constraint alone severely limits the number of drives available for selection.

Among the slower HDD options, the Seagate Barracuda Green (1, 1.5, or 2TB @ 5900 RPM) and the Western Digital Caviar Green (1 or 2TB @ 5400 RPM) are the recommended choices, and Digital Connection even offers to bundle one of them with the TViX, if you buy the unit there. The problem with these drives is that on sites like Newegg that have more than 100 reviews, nearly 20% of those reviews said that the drives were either dead on arrival (DoA) or would die within a few weeks. I don't know if this unreliability is related to the floods in Thailand, but considering how much HDD prices have risen lately, I considered those failure rates to be too high to take the risk of buying one of those drives. Another theory is that it seems like HDD manufacturers have tried to raise the capacity of drives faster than they've been able to perfect the technology for sustaining those capacities, so high-capacity drives have a higher likelihood of failing than drives with < 1TB of storage.

The other route you can go is to buy a laptop HDD, as most laptop drives are designed for low power and heat generation to save battery life, which makes them ideal for DVR usage. The problem with going this route is that the TViX drive bay is designed to hold a standard 3.5" drive, while laptop drives use the smaller 2.5" form factor. As a result, a laptop drive won't simply slide into the TViX; installing it requires you to put the unit on its side, slowly lower the HDD into the drive bay, align the connectors, and push it into place. Once it's locked, the 2.5" drive needs some kind of wedge or support system installed underneath it, or else it will dangle and eventually bend and damage the SATA connector inside the TViX over time, because there's about 0.5" of clearance between the laptop HDD and the bottom of the drive bay. There also don't seem to be any "official" adapters for this type of installation, as most 2.5" -> 3.5" HDD adapters are meant for computer cases and assume you're using SATA cables, rather than a plug-and-play configuration.

If this all sounds less than ideal, that's because it is. HDDs are expensive right now, and the selection and quality seems fairly low, too. All I can tell you is that after considering the above, I opted to go the laptop HDD route. I figure it's not worthwhile to get the extra storage capacity of a 1-2TB drive if it's just going to die after I load it with 1.5 TB of content. As such, I opted to get a 500GB Hitachi Travelstar 5K500.B drive and klouge together a mounting system for it inside the TViX. If you look at earlier posts in this topic, I think you'll also find someone who inserted wooden wedges into his unit to keep a 2.5" HDD steady. (You need something that will support it and also prevent it from working its way loose from vibration.) Although the laptop HDD solution isn't particularly elegant, it has the significant benefit of allowing for excellent air flow around the entire HDD, which you can't get with a full 3.5" drive. My TViX has been recording for the past 30 minutes as I write this, and the air coming out of the fan vent is still barely warm.

I hope this deluge of information is useful in some way, even if it isn't what you were hoping to hear.
post #1491 of 2239
Aleron,

Wow...

Thanks for taking the time, to write such a comprehensive reply to my earlier post.

You hit on a number the key elements, that I have also have concerns about myself...

The number one concern in my book, is the very troubling decision by HDD manufacturers to push the envelope, and focus on building huge capacity hard drives (1TB-2TB), ...while the underlying technology to make those drives as reliable as possible is lagging far behind the curve. The short term/long term failure rates are totally unacceptable on many of the 1TB drives that I have researched. (in my opinion)

That data tells me, that manufacturers are clearly focused on the wrong end of the HDD technology front, and I hope the shaky reliability problem is given more attention in the near future.

The huge capacity hard drives available today, are a boon for us as modern HDTV PVR owners. But...that's ONLY if those drives can survive the torture of this type of extreme duty. You're right about the SPEED of these drives being a problem in these devices.

HIGHER SPINDLE SPEEDS (7200rpms) = HIGHER SUSTAINED DRIVE TEMPS

HIGHER SUSTAINED DRIVE TEMPS = INCREASED CHANCES OF SERIOUS RELIABILITY PROBLEMS (short term & long term)


I was already looking to buy my TVIX unit from the Digital Connection, and I was hoping the reliability of the WD 2TB drives might be "much better" than the larger capacity WD drives I have reviewed in the past couple of years.

It seems the reliability of these new WD 1TB+ drives, isn't really that much better today, than they were two years ago. (which is discouraging)

The surprising number of hard drives that arrive at your doorstep DOA is equally troubling, and absolutely unacceptable in this day and age. It seems the quality control inspection process at these factories is completely broken, or the people in charge are alseep at the wheel.

I was hoping that large reliability gap (vs. the smaller capacity drives) would have been closed in some significant fashion, since these larger 1TB+ drives have been around a while now.

It appears that hard drive manufacturers haven't found any real innovative solutions to solving these reliability issues (as quickly as I would like to see), ...so I'll either have to roll the dice on one of the two 5400-5900 rpm full sized 3.5" drives that I've been considering for use in the M6620-N, ...or use a modified 2.5" laptop drive like you proposed.

I have to admit, that I'm not exactly thrilled about the prospect of using a laptop drive in my new TVIX PVR. I understand your reasoning, but the extra work necessary to fit the drive in the HDD bay properly (and the severely reduced capacity), are not making me all that warm and fuzzy.

It certianly is an OPTION that I may need to consider though...

Thanks for the reply Aleron, and I hope others will chime in with their take on which HDD they selected. (and why)

Whatever ION is doing is probably not illegal. They have 50 stations. What if more stations do whatever ION is doing? I don't have it disabled since my cable feed strips the damaging part, or the damaging part is not yet added to my two ION channels. Time will tell.

I guess I am another +1... I purchased the DVR with the latest firmware. I have not found any pattern to when the system seems to set the skip intervals to 0. I do not know what else it is loosing but it does maintain the channel list and the wifi ssid/etc. It is an aggravation.

The AirBox service is perfectly legal; the FCC allows broadcast stations to provide such services. The problem lies in the TViX firmware, which rather than ignoring the PSIP information for the extra MPEG-4 subchannels, crashes when it detects them. You won't have any problem with getting ION over QAM, because AirBox is OTA only. QAM also doesn't provide PSIP to crash the TViX.

Also...

Not that anyone probably cares, but I think I found the pattern for this. If you turn the TViX off when it's in HDTV mode, you'll see the "TViX Power Off" logo on the screen, and the "Saving" message on the front panel will be bright. If you turn the TViX off when you're browsing the HDD contents, the "Saving" message is displayed at half illumination. Oh, DVICo.

@ Sean

Laptop HDDs are available in sizes up to 1TB, but IMO the increased stability of a 500GB drive is more desirable. That's still enough capacity for ~75 hours of recording, which sure beats the VCR I was using. Besides, if you really need the extra capacity for some reason, you can buy multiple 500 GB drives and swap them out. Just remember that you don't want to wear out the SATA connector inside the TViX by switching drives too frequently.

You could also buy a single 500 GB SATA drive and two 500 GB USB drives, then connect the external ones to the TViX's USB ports. You can't record directly to USB, but you should be able to copy files from the internal drive to the external ones to archive your material. If you don't want to buy three drives, just use FTP to transfer old recordings to your computer and set up TViX file sharing so it can play the files stored on your PC over the network.

All cable is local. Some do have PSIP. The CM7400 says it works with MPEG4.

Next: RCA DPH-1000R-HD. Thread started. Rock has been turned over.
post #1496 of 2239
It's my understanding that QAM has no built-in method for delivering program names and titles, so all cable companies that want to offer program information for QAM have to do so through a separate means, although I don't know what that is. Since AirBox isn't available over cable anyway, there's no chance of the TViX crashing from an ION QAM feed. The TViX is also able to play MPEG-4 files, but MPEG-4 is not valid for ATSC broadcasts. The MPEG-4 subchannels on ION stations are broadcast using encrypted MPEG-4 anyway, which is why viewing them requires you to rent a box from ION. It's not the encrypted channels themselves that crash the TViX; it's the information about them in the station's PSIP data that the TViX doesn't like.

FWIW, the TViX isn't the only unit that can get confused by PSIP data. My LG television crashes from the PSIP data on one of my PBS stations during certain programs. If I try to view the program information, the window never appears, and the TV spontaneously shuts itself off. Sound familiar? The power indicator doesn't change when the TV dies, so it isn't a proper shutdown when this happens. Thankfully, I can still watch those programs as long as I don't try to view their information, and the TViX handles that particular PSIP data correctly.

On another note, you've said, "All cable is local," in multiple topics now. What do you mean by this? Most cable channels are certainly not local, as the main point of having cable is for its non-local channels that aren't available OTA. If you mean to say, "All my cable channels are local," that would make sense, if you have the basic cable package that only provides you with your local channels. I must be missing something.

To keep it brief, I never said "channels". My "local" channels could be NY, Philly, Harrisburg or Scranton-Wilkes-Barre. I guess the FCC figures that since I could erect a 500' tower, they are HD clear QAM. So is ION SD digital from Williamsport. Every cable headend is controlled by the local office. Eight miles from here the lineup is totally different, with 70+ basic vsb/analog channels, like TNT, and 160+ clear QAM. For me TNT is a QAM digital 480i channel only since 2009. I can get it in HD for more money. This is from the same corporation that owns many headends that service middle PA to middle NJ. It can be confusing.

As for PSIP, I often wonder why my little 4:3 Sanyo HD digital TV shows "CBS" on the CBS vsb/analog channel 2. SCTE-127? I don't know. I also get CC on digital channels and my Sony DVR can record it.

Local cable just means that the headend & local office controls what you get, how you get it, and where you get it. They are all different. Sometimes an apartment complex or trailer park will contract with a cable company for service and a STB isn't needed. There are many variations. My little cable company even publishes the raw clear QAM channels on their BBS channels when something is going to change, and tells us subs with QAM tuners to do a rescan. Of course, things always change. I hope I have explained myself better this time.
post #1498 of 2239
Thanks, that helps. I'm not very familiar with how cable networks are structured, since I strictly use OTA TV.

In TViX-related news, I found out it's capable of playing files in slow motion by accident this evening. "The more you know", I suppose.

Fixed it. The problem was PEBKAC. Sort of. I was not using the Record Schedule function properly, I guess. Took a while to realise what I was doing wrong.

The problem was in the user interface. When setting up a recording Schedlue entry, you can use the Next and Back buttons to navigate between the two setup screens. But when you go back to the first screen then return to the second, the PVR forgets the recording cycle and always resets it to "once". Without carefully re-specifying the recurrence cycle, e.g. to "Every day", and thereby working around the bug, I was getting the original behaviour I described.

Someone above mentioned submiting bug reports to Dvico. I have done the same and heard nothing back. Someone else mentioned that Dvico does not monitor this forum. Which is sad really, since this is where the action is as far as user observations and suggested bug fixes and improvements for Dvico's products.
