Official DVICO TViX M6620N HD (ATSC/QAM) Tuner Topic - Page 40

post #1171 of 2110
Also - I noticed last night after d/l-ing some new cover .jpg's into my movies folder, the TViX shut itself off every tie I accessed the folder.

Trial and error revealed two .jpg's that cause the TViX to crash. Very weird - I will continue to experiment and report results.

The screen just says "Unsupported format". I had never deleted them thinking that some update would include their codec. I believe they are 720I if that helps. Is there likely some trick I can do to make them play?

As you may know already, "WMV" is a container like AVI and MKV. As such, it can contain many differently formatted video and audio streams. I happened to find several small WMV files here just now and (as reported by MediaInfo) 3 out of 4 of them turned out to contain VC-1 (WMV3) video streams that played just fine on the TViX. The 4th one had a WMV1 video stream that was "not supported". Very likely you can recode your wmv files with some tool such as VideoReDo or Windows Movie Maker and recast them in a TViX playable format.

Possibly these are interlaced JPG files? ISTR that TViX doesn't cotton to such.

How to I tell if they are? I tried editing them thinking that would clear a bad header, but no luck.

If you were using a proper computer, I'd know what to tell you to use (Irfanview) to save the offending JPG to a TViX-friendly format. All I can suggest is that you load the file into whatever picture display app you use on the Mack and then use its equivalent to "Save As" to specify that it be written as a "normal" JPG file.

I am using a proper computer - just not a proper OS Proper computers are like air conditioners - neither work well when you open Windows! I'm a dot-slash geek, currently running Kubuntu. But back to the topic...

I tried opening the jpg with GIMP editor and trimming a bit off and re-saving it. This didn't help. I've had no problems doing this so far (about 300 covers created without issue).

I haven't ever seen an option to interlace a jpg so I honestly didn't know this was an option. I'm not much of a graphics creator. I'll try saving it in a different format and then re-saving it as a jpg tonight and see if that fixes it. The file headers look normal.
post #1177 of 2110
Well, it seems that I misspoke and the offending JPG type is likely "progressive" rather than interlaced. See the attached cap of the Irfanview Save-As options.

Your idea to save in another format and then resave the saved file as JPG will probably fix it.

This one comes close, I think.

It cost a little more and has a much smaller hard drive (than the Tvix I bought anyway). But that won't be a big deal if the hard drive is removable. I don't know if it is though.

I am posting this to remind Dvico there is a competition for their market. If they are not improving, the competition might catch up to them.
post #1179 of 2110
Definitely the same kettle of fish. The previous model didn't have QAM tuning, but the CM7400 does. (But the similarity may not stop with the desirable traits--I note that the CM aka DVPal boxes have also had user complaints on AVS Forum re. crashing. )
post #1180 of 2110
That machine has some features the Tvix could borrow from such as a front panel USB port and eSATA connection.
post #1181 of 2110
Yeah, check out the next-gen TViX A1 for those. (The ports are on the side rather than spoiling the clean look of the front panel. Also, the A1 is a player only, with no tuner(s), but you can get the idea of where Minevox is going)
post #1182 of 2110
The previous Channel Master products really stunk based on the reviews I read. This new one will be one to watch, thought.

RE: The jpg problem I'm having - I copied one of the offending files to gif and then back to jpg and it still crashes the TViX
post #1183 of 2110
I have had JPG files causing the Tvix to crash before. The simplest solution is just to delete the file.

It handles corrupted video files better. Instead of crashing it will just jump to the next video.

This right here shows the consistency of the codes used in the TVix.

True, but there really isn't a big demand either. That's one of the biggest problems with an EPG, if the manufacturer has to pay up front, and monthly, it can get reallly expensive so sales have to consistent.

2. Open Source does not mean without license. Anyone who applied their software outside of it's license would be subject to legal action and they could open things like the menus and function without releasing driver source (unless they found a need).

With work, their firmware has been reverse engineered. Unfortunately, the guys who do this stuff are outside legal jurisdiction. The only fix to this is ever chaniging code and updates. For instance, there are locked Korean models that sell cheaper in their market. They can be cracked and sold, but the subequent firmware update breaks the English menu.

Quote:


3. The fact that the software was readily modifiable would be huge plus for sales.

And possible headaches. Firmware has been known to brick media players.

Quote:


4. The cost benefits of freely enhanced software would likely increase hardware sales well beyond any loss due to piracy and they could (via a proper license) incorporate any improvements created publicly into the delivered software without cost to them.

That's one of the reasons why Minevox is focusing on the Android platform. It would let programmers write apps that can be distributed freely, and some possibly as a purchase.

Quote:


5. Anyone with the desire and skill to build their own "home-brew" dual tuner DVR has plenty of freely supported software available. So why rip off this software which is generally inferior to others available?

If you look around, there aren't many great ATSC tuners that can record. And when they can, the recorded content is often difficult to access. Aside from a PC, that is. Minevox/DVICO started in the PC business, and staked their future in the media box with the knowledge they gained building PC cards for US consumption, they are one of very few companies that understand the broadcast system here. Note, Korea is the only Asian market that uses ATSC, specifically so they could export here. The TV market is not friendly to anyone outside the major service providers and their hardware vendors.
post #1187 of 2110
Hi All,

Just happened upon this forum as I've contemplated buying an over the air ATSC tuner.

I tried searching through this forum but didn't see any recent reviews of the TVIX M6620N plus.

1. WHat is the competition out there other than the Channel Master?

2. Are most of the firmware/software issues fixed?

3. What is the user experience on this model? How are the menus, navigation, etc?

4. Are shutdown issues still prevalent?

5. What is the firmware support for this model? Is the manufacturer or community actively supporting it, and for how long?

6. Is this product nearing it's end (another over the air tuner box in the works with Android OS)?

thanks much,
sp

Not many. All available recorders are probably being disucssed here in one of the active threads.

Quote:

No, not all. And there are couple of function/features like the recording dialogue and CC that may not happen due to hardware limitations.

Quote:


3. What is the user experience on this model? How are the menus, navigation, etc?

There are comments peppered through out this thread.

Quote:


4. Are shutdown issues still prevalent?

Aside from the now discussed .jpg shut down (not sure why that's happening), and the ION channel station introducing the second problem this year, no.

Quote:


5. What is the firmware support for this model? Is the manufacturer or community actively supporting it, and for how long?

The firmware updates have been ongoing since this thread was first started two years ago.

6. Is this product nearing it's end (another over the air tuner box in the works with Android OS)?

Possible, depending on how soon the new chips can be tamed. Implementing tuners on media player processors is no trivial task, and Android will be even more difficult as an OS.

Thanks for the detailed response, Kei and I think all your points are very valid. Any chance you'll be at CES next month? Ill be looking at all the A/V offerings!

So how does one record say the show "Bones" for the season. With my tivo I just setup a season pass and all done.

Is it something I have to set on a weekly basis?

I looked at the manual but it didn't give me enough helpful info.
post #1192 of 2110
Like I said, there are no season passes. You can record a weekly show by setting up the first instance via today's EPG and then editing it from a once to a weekly frequency. It's rudimentary at best.

EDIT: But on the plus side, the box ain't burning up 40 watts day and night 365 days a year, the way your TiVo does, either!

Please check Amazon for product reviews on the CM7400. The drive is not removable and the eSATA connection is not enabled. Good luck.

If we are watching a recorded program on the M6620N, and a timer is getting ready to start recording a new program, a countdown alert box pops up. At the alert box, it seems like I either have to cancel the new recording or when the timer goes to zero, the DVR will stop showing the recorded program we are watching and switch the playback over to the new channel that is being recorded. Is there any way to prevent this behavior and get the M6620N simply record the program in the background without it switching the playback?

This thread is full of complaints about this behavior. It suffices to say that the engineers are aware of it, but they don't really communicate much. Hopefully, this will be fixed in the next update. This even happens when you're watching a recording (nut even using one of the tuners) which is really aggravating.
post #1196 of 2110
I'm not sure why, but yesterday I noticed my box was off. When I turned it on, it started at the Menu which usually means it crashed. Sure enough, I was unable to watch TV on any channel.

I would select Live TV, pick a channel (I did this several times) picking a different channel each time, and in about 30 seconds or less the box would shut off. This was different from the Ion TV issue in that the guide was populating correctly and everything seemed normal.

We gave up after the fourth try and watched a couple recordings instead. About three hours later, I was headed to bed and tried it again - and it seemed it was back to normal. I haven't tested it this morning because my daughter got up early and started a movie.

EDIT: All OK this morning, odd...

Boy, if you just look at the company site you'd buy it. The Amazon reviews show it's true colors. Too bad as it (supposedly) has a lot of features missing from the TViX.

Yeah, pretty web site. I had mine for about 18 hours. At least UPS made some money.

I'm about half way through reading all the posts on this thread. The TV9 manual mentions an internal HDD (Page 11). Did that every happen?

"TV9 manual" is too generic for Googling...what are you talking about? The M6620N certainly supports an internal HDD....

Roman numeral. It's hard to joke on the internet.

Spec says:

Caution:
- HDD is not included.

Manual says it has one. Must be old spec. Thanks for the information.
