I'd still like to know just out of simple curiosity. Is it something with the TV or the 3500STBII?

Thanks.

Well you could try an alternate composite video out device, say a cable/sat box, disc player, etc., and see if that successfully shows up on your TV display. If that alternate device does, then this implies the issue is with the iView or one of its settings. . . It would seem weird to me that this would matter but make sure your iView output (when attempting to use composite) assuming this is being used with a US TV, is set to "NTSC", not PAL, "480i output resolution", "USA TV signal", and anything else I may be forgetting.

In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".

M. Zillch may be onto something. Hook up the iView via component, then go to Menu / Picture and check the TV Format setting. It should be NTSC; if it's set to PAL, your TV won't be able to lock onto the composite output.

It was set to "NTSC", "1080p output resolution", "USA TV signal". Since I'm doing OTA, I want the best resolution available, so I'm sticking to component and saving the remaining HDMI input for future use.

Thanks.

OK sounds good. Composite (if it were working) is always 480i (in NTSC mode) or 576i (in PAL mode), regardless of the resolution setting. Component and HDMI will give you whatever resolution you have set (1080P in your case).

The iView outputs HD content in both SD (via composite & RF) and HD (via component & HDMI) at the same time. It shouldn't be necessary to set the resolution to 480i just to get composite to work (although that is necessary with some devices other than the iView).

Perhaps you can try another composite device sometime, just to see if the problem with composite is on the iView or the TV - but since you can't use composite and component at once on your TV anyway, it makes sense to use component and not worry about composite that much.

still spending $thousands to make a $40 box work - part 2

A few updates to my experiences with the original iView 3500STB that might be of help:

1. I bought an RCA 6-device remote (RCRN06GR) for about $10 and after the typical nightmare of trying to program the thing for all my devices (particularly using learning mode with the old iView remote), it solves the horrible remote problem, and actually enhances it. I got this particular remote because it has page up/down buttons so you can look at the second page of guide program descriptions in the iView (and it more fully revealed the bug that if you page down, the next programs will also have the program description on the second page, so remember to page up). An enhancement: for whatever reason, after I first got my TV remote programmed using the automatic built-in codes in the universal remote (the only built-in codes that actually worked for any of my devices), I found that the audio volume up/down buttons, which did nothing on the iView remote, actually control the volume of my A/V receiver through the TV HDMI. So a simple, cheap, but not perfect way to integrate your entire A/V system. I had previously used the trick of putting tape over the IR receiver on the iView, which seemed to help the aiming and range problem a little, but the RCA universal remote works just like a real professional remote with quick response to button presses from all angles and distances.

2. I found out that my Toshiba TransMemory ID 3.0 flash drive did NOT handle all aspects of iView recording operations properly. Pause had some glitches, which I don't use anyway and assumed wouldn't work perfectly. But I found out the hard way that a 1080i station with no sub-channels also had glitches when recording(every other channel on every other station was fine). So I guess the write rate of the flash drive is just a LITTLE too slow for the full data rate of a DTV station.

3. To that end, I was looking to use a powered drive, and was specifically looking at a Seagate 3TB Expansion drive. So I got one, hooked it up to the iView, and found the iView would not even boot. I do believe the problem is that Seagate uses GPT in their firmware (they say as much), and the iView requires the old MBR partitioning scheme (note that this would seem limit the iView to an effective capacity of 2.2TB, no matter what the size of the drive). I hooked the drive to my Windows 10 machine and it works fine and I was actually going to buy one for that purpose in the first place, so I don't have a 100% DVR storage solution for the iView right now (I've reconfigured and repositioned my old Windows machine in the living room entertainment center to use Windows Media Center (banned by Microslop from Windows 10) for DVR duties, which it did well in the first place. But I did like the iView because it actually had a guide that you could use for recording (officially Windows Media Center currently does not, there may be a hacked workaround out there). So I'd like something other than my 1TB/2TB USB-powered Seagate drives, which work pretty well for everything, but cause the iView to run very hot/hot respectively, so I don't want to use them long-term.

4. Audio/Video disconnect that I noted in some MPEG files in the iView turned out to be the result some new video editing software I was using on my new Windows 10 machine, because I could replicate the problems on other USB media playback devices, such as my TV. So I have a slight problem in that my latest and greatest Windows 10 is not all that great in terms of OTA recording and editing videos, which is another example of how in some cases technology keeps getting worse rather than better...

Does anyone still have the V13 version of the firmware that used to be available for the 3500STBII? I just download the version that is available on IView's site for the 1309 and now every time that I power off the box can't get any signal until I unplug it completely from the AC. If anyone has or knows where I can get the old V13 please let me know. Thanks

Hey Anthony..
I believe that I have v13 from back then. I saved all the firmware when the 3500STB first came out. I had a feeling they'd all disappear over time. The version I have..
It's V13a, dated 12-27-13. If that's the one you need PM me your email and I'll send it to you.

As far as the update on my 3500 and 3500STBII situation. Just to let everyone know, even you JHBrandt (thanks for the help!). I did email iView but they are very slow in responding, so I'm just going to send the 3500STBII back for a refund. Don't want to be stuck with it. I ordered a second 3500STBII thinking it might get better but it is definitely not as bright as the Channel Master 7003 or my original 3500STB. I did flash the latest firmware to the STBII but no not going to keep it when the 7003 is much brighter on the composite output.

Thanks for the kind offer to send me the V13, and yes, I think that is the one that I need; however, I just tried to send you a PM but it wouldn't let me as it said I didn't have enough posts to PM yet. You can send the firmware to new_age_guitarist at hotmail.com. My email is all over the net anyway, so no problems. Thanks again for doing this.

I have all three versions of the 3500STBII but I have only used them via HDMI, so I can't comment on your brightness problem. Sorry to hear that it didn't work out for you. I emailed IView over a week ago about this firmware issue and they still haven't gotten back to me, if they ever will, so you're spot on---they are definitely slow to respond. It doesn't seem like any of the companies that make these little boxes have very efficient customer service

V13 for the 3500STBII isn't on their Web page anymore, but it can still be downloaded directly from iView at http://www.iviewus.com/download/firm...ll_flashAA.bin. They just removed the link from the Web page; they didn't remove the firmware file.

I don't know who put that "1309" version on their Web page. That does nothing but confuse people. I checked it a while ago and once you unpack it, it's just a copy of V1 - which is already listed further down the page!

Hey no problem at all, that's why I keep the older versions, you never know when it might be needed. I did send you an email, all set. Let us know how that works, I'm pretty sure that's the version you're looking for since I saved everything from back then.

Yeah iView did ask me which models I had, but that was about 2 weeks ago. The time was ticking to get a refund on the 3500STBII so I didn't think I was going to wait around for iView. Now if they can come up with a fix for my 3500STB fine, I can wait. That problem is some frequencies are missing from the QAM line up. Where the newer MStar 7802 boxes can pick up my older 7816-based box cannot. Very odd. It's only missing a local channel anyway, and I never watch that channel, so it doesn't matter that much! lol, just like to get it fixed.

Well at least we know that you haven't had any HDMI issues. Yeah this was quite obvious from the moment I plugged it in that it was half-brightness on the composite video output. I did flash to different versions and it brightened it up but nowhere near what my original 3500STB (nice and bright) or the CM-7003 (channel master) is. Oh well.. At least I have the 7003 as a backup.

I did remove the "usb_upgrade_all_flashAA.bin" and was able to access the rest of that directory. At the bottom I see the file you're talking about. I wonder.. the one that says usb_upgrade_all_QAM.bin, is that for the 3500STB or it's for the 3500STBII? Not that you know JHBrandt just asking if you did know.

Yeah I had to stop and think what they meant by 1309, then I realized it was part of the serial number!

That QAM firmware version is very strange. I extracted the ID strings with a hex editor:

Model: ATSC - TEST
SW Version: CL630133 130618 V7
HW Version: KLF7816-ATSC-01

It's hard to tell much from that, other than that it was written for 7816 boxes, and (from the [20]13 06 18 date - six months older than V13) it's probably for the same boxes (with the Samsung demod chips) as V13. (Maybe some of our iView old-timers will recognize it.) So it probably wouldn't brick your 3500STB, and might even work. But I don't think it was written for it.

I think it may be generic firmware, before iView customized it to their box. It's probably a mistake that it's on iView's download server at all. I don't ever remember seeing a link to it on any of iView's regular download pages. I can't imagine an older version would tune more channels than a newer one, but stranger things have happened with iView.

That download page doesn't show file dates, but all those usb*.bin files have been there for as long as I can remember. There is no new firmware for older boxes there. As I said before, iView can barely handle maintaining firmware for their current boxes! Maintaining firmware for old boxes they aren't making money on any more (and are long out of warranty) is probably too much to ask.

Yup I do have that version, thanks for checking it out "internally" to see what it was. I have that version dated 6-18-13. I have used it, there were two versions both were trying to make the "QAM Physical" work better. I've alternated between V6 and V7 of the QAM, and they're about the only ones that actually will tune my cable's QAM in at all. What I have done to make things work is install the latest version of firmware for the 3500STB called "all flash V6" but it's not the V6 QAM Physical, it's a different V6 (very confusing). But I installed that, did a factory reset, then re-scanned for the channels. This newer version will ignore all the scrambled, non-QAM channels, plus it will give the network named to all the channels, not just the channel number.

On some of the local ota re-broadcasted channels, the program guide actually works for once, at least on cable!

Once this latest version is installed, I re-flash to V6 QAM Physical but I don't do the factory reset. Then I can tune in the other channels that are pixelating under the newest firmware. I know it's a half-n-half solution but it's what I played around with and found works to get the majority of the stations on my cable system.

Thanks again for looking into that firmware, I really appreciate the help!

Also, I agree, I don't think iView can handle the CURRENT firmware, forget one that is going on 4 years old! I think I'll keep the CM-7003 around just in case this 3500STB has more issues.

I just bought another 3500STBII (#3 ) to supplement my current unit (#2). (#1 gave up the ghost.) Both are for ATSC reception, but the new unit is connected to a different indoor antenna.

It works properly for manual recording. But it will not do scheduled recording. I thought perhaps it was a question of the USB drive (a 2TB Seagate USB3). I tried the 1TB Toshiba USB2 drive that I use with STB #2. Scheduled recording does not work with this either. In both cases it displays the starting booked event message, but it never really records nor does it display recording time in the upper left corner (as it does with manual recording).

As expected, unit #3 will not play back MTS files recorded in "PVR" mode on unit #2. This is inconvenient, but inability to do scheduled recording is a serious issue.

Thanks so much for sending me that firmware. It worked like a charm. I was actually reading through the thread on the Channel Master box and I saw your posts there, as I was looking into replacements if I couldn't get this box to work again. I read about the issues that you and others were having with it; it seems that all these cheapo boxes have their faults, so everyone just has to decide which faults are better for their given situation. Brightness issue aside, do you like the Channel Master better or think it is of higher quality?

You have made me curious about the composite issue. Tomorrow, I am going to try all 3 generations of the box with the composite output just to see if there is any differentiation in the brightness levels. Do you have the new version of the box with the green LEDs?

JHBrandt, thank you also for the link. I think I am going to save a backup copy since I know this firmware version works well for me. I probably won't be trying to upgrade that box again since I doubt IView is even actively working on improving a box that old and I really don't have any major complaints about V13 for my uses.

Thanks again to both of you!

I just got the 3rd generation box about two weeks ago and I had the same problem with scheduled recording with the firmware that came on the box. I downloaded the one from IView's site for the 1604, and installed the one marked flash.bin, and then I had the issue of no sound after reboot and the aspect ratio was incorrect. Once I installed the one called usb_uprgrade_all flash.bin, it worked as expected. It has been virtually trouble free since then, so perhaps that can help you too.

As far as playing the files from the previous versions, all you do is rename them with an mp4 or avi extension and you'll be able to watch them on your new box.

HW Ver 78021237836650

One scheduled recording (out of many trials) DID work. This was set from the EPG, but of course it missed the beginning of the show. I always schedule manually to start at xx:59 to avoid this problem.

It seems that it takes this box #3 much longer to start a recording than I was used to with box #2. Perhaps the scheduled recording is failing if the drive does not respond soon enough...

A minor irritation: When changing channels, the program information stays up almost 15 seconds -- much longer than with box #2.

Got it. That date matches the 1511-EPGFix version on iView's web site.

LH92037 had a similar issue with that firmware version; installing the 1604 version (dated 20160923) fixed it for him:

JH .. The 1604 f/w update solved both my "Add Event" bug and failed recording problems (without having to purchase a new thumb drive). As you noted, 1604 has a few minor bugs, but no deal killers.

If installing 1604 doesn't work, try setting up a dummy 1-minute recording just before the "real" recording. Of course you shouldn't have to do this, but if it's a problem with the drive spinning up too slowly, that would probably fix it.

Regarding the program info window, I have a similar issue with my DVR+. I've just gotten used to hitting Info twice, but I wish they would make the time it displays user-selectable.

Actually there are two possible problems that can cause this:

  1. GPT vs. MBR partition table. Luckily, this is not in the HDD firmware, but is part of the boot sector. That means it can be changed (e.g., on a PC). However, changing to MBR will limit you to about 2.2TB, so you'll lose about 25% of the HDD capacity if you do that.
  2. 4K sectors vs. 512-byte sectors. Modern HDDs use 4K sectors, but for compatibility, the HDD's firmware normally simulates the older 512-byte sectors. However, some USB-attached HDDs reverse this simulation and present 4K sectors instead of the simulated 512-byte sectors. This has advantages (e.g., you can escape the above limitation, accessing up to 17TB even with an MBR partition table), but 4K sectors are probably not compatible with the iView.

Brightness issue aside, do you like the Channel Master better or think it is of higher quality?

You have made me curious about the composite issue. Tomorrow, I am going to try all 3 generations of the box with the composite output just to see if there is any differentiation in the brightness levels. Do you have the new version of the box with the green LEDs?

Thanks again to both of you!
I've been away from this forum, sorry for the delay in responding. Were you able to try the composite output on all of your boxes?

I'm trying to remember what color was on the 35000STBII front display LED's.. you know I can't remember. I know that the serial number began with 1609, and it did not have a physical 3/4 channel switch. My original 3500 has the red LED display and the channel master cm-7003 has a yellow/amber color.

And you're absolutely right, it's like we accept the faults/bugs for what they are and try and work around them. I found with the CM-7003 if I just leave the original channel scan order and not arrange the channels, it does not try and reboot to rearrange them. Oh well. I did return the original CM-7003 because I wanted to see how another unit performed. The replacement still did the rebooting so it's definitely inherent in the firmware for QAM tuning.

As far as quality.. The remote is terrible, small buttons you have to push hard (and yeah i've tried 2 of their remotes). I'm probably going to get a universal remote to learn the functions. The 3500STBII remote is the best of all of them, it's very responsive and I don't have to point it directly at the unit to work. And if I want to page ahead in the channel linup I can do that with the 3500STBII remote. I have to push the channel up button (or hold it) on the cm-7003. Kinda of annoying.

The one thing that is better on the cm-7003 is the odd re-tuning issue that I've had on the 3500STB. For example, I've tuned to a channel, begin watching, then within seconds it re-tuned that same channel! Screen goes blank, channel display/description comes up, image of channel is back up. It will also happen when the local cable co. injects local ads. That has been greatly minimized with the cm-7003. But all of this is talking about QAM cable tuning, not over the air. Since I am only using it to avoid paying for a set-top box.

So how's your 3500STBII running after the firmware I was able to send you? Is it back to normal?

Every iView and HomeWorX version I've tried has this annoying bug, even OTA. What's especially bad is that not always, but often, when the box re-tunes a channel like this, it actually re-scans the channel, as if you had gone into the menus and had done a manual search! That means any subchannels you deleted or skipped come back, any you favorited lose their favorite flags, any you renamed revert to their original names, and any timers you set up for any of those subchannels disappear.

So it's encouraging to hear that the CM-7003 has dealt with this, at least somewhat. Edit: The iView 3500 firmware at http://www.iviewus.com/download/firm...PGFix_1511.rar seems to have the same fix. I now use it on my iView 3200 for that reason. A major improvement IMO.

Thanks JHBrandt! That's exactly what it is doing!!! I tried my best to explain it. But it is definitely re-scanning, as if it said "oh wait, this channel is new, let me add this.." lol.

And you're right the cm-7003 is a bit better, I have had that re-scanning happen a lot less. It will only happen now if the cable company injects one of their local ads over the regular tv broadcast. But it doesn't re-scan the entire, re-enter the entire channel (about 5-6 tv channels per cable channel/frequency). It will only happen to the channel I'm watching, not the entire line up. So that's a bigger improvement. And as long as I do not re-arrange the channels, no rebooting either. So looks like I've been able to work through the bugs the 7003 has to make it "workable" for me.

But thanks for clearing up its behavior, I definitely learned more about this!

Oh I also wanted to tell you that I have been counting how long the boot-up sequence is. And yup, cm-7003 is at about 12 seconds. My older 3500STB is about 8-9 seconds. But at least I can tune the missing QAM channels now with the 7003.

Back with an update...
Thanks very much for your help guys, but...

I took iVIEW box #3 out of my system today and put my Samsung ATSC tuner back in operation. While sometimes the iVIEW #3 had adequate reception, it was very often unable to get a good signal on my PBS station.

I'm in a high rise condominium and the transmitters are blocked from direct view. In the last year, two new high rise apartment building have been built within three blocks which are in the direction of the transmitters. I think this is why box #2 no longer is able to get good reception on several channels.

Two TVs and iVIEW #2 use rabbit ears + UHF loop antennas. The Samsung (and iVIEW #3 ) uses a (discontinued, very directional) Silver Sensor antenna. Positioning of all of these antennas is quite critical.

Well, the Silver Sensor is moderately directional:

I wouldn't say it's "highly" directional, but it's decent for indoor use. BTW, the Silver Sensor may be discontinued, but I think the very similar Terk HDTVa is still available. The HDTVa includes rabbit ears for VHF.

Which model Samsung are you using? I used to use an old DT-260F that died several years ago - then I discovered it wasn't available anymore (except used on a site like eBay). Those were great!

When it died, I tried a CM-7001 (which I HATED) before finally settling on a HomeWorX (iView clone). I have had some trouble with the HomeWorX tuners, but I'm lucky enough to have a big outdoor antenna that mostly makes up for its weaknesses.

Well I'm going to have to take back everything I said about the cm-7003 and even update my posts over on the cm-7003 thread.

I went to turn the cm-7003 on today, and it would not stop rebooting. I unplugged it from the wall, waited, plugged it in.. Nope, that didn't fix it. I did a factory reset via the menu, nope that didn't fix it either. Every 3 minutes it continued to reboot, also locking out any ability to turn the unit off via the remote.

So that's that, I'm done with the 7003. This is my second unit and both units exhibited similar behavior after a couple days of being used. I'll just return this for a refund and use my original 3500STB. I will have lost two local channels, but oh well, at least it works.

iView's tech support has never emailed me back and I don't expect them to. Channel Master was pretty much useless with their tech support. I had asked for their original firmware but the excuses were to just do a "factory reset, it's the same thing". um no, it's not. I doubt they even have access to the firmware. Their solution was if the factory reset didn't work to just buy another unit. Great advice, lol.

Thanks to everyone for the help, especially you JHBrandt! I guess I'm lucky to have a 3500STB that doesn't reboot and is stable, other than missing some frequencies in the tuner (hence the two channels missing after the cable company re-arranged the QAM lineup). But I can't justify wasting money on a unit that continues to reboot and nothing I do can stop its behavior other than returning it.

Major bummer - I was pleased to learn their firmware finally addressed the channel rescan issue, but that constant rebooting is a show-stopper, at least for QAM.

In the past, I'd casually recommended a Samsung gx-sm530cf for QAM, but I just priced it and it's outrageously expensive: $399! For that price you could get a TiVo with lifetime. Or ten HomeWorXes! Good grief.

I tried to get the answer with an Internet search - but every pic of the 3500STBII I could find was turned off! So I couldn't tell the color. (I don't have a 3500STBII myself - I have a 3200STB without a display.)

I did notice that most of the clones with displays I found (Boost Waves, eMatic, ViewTV, and of course the CM-7003) had amber displays. One ("Vilso") had what looked like a white display, and one ("Koramzi") had a green display.

The DTB-H260F. Purchased early 2007. The first one was defective, but the replacement is going strong.

USB Hub compatible?

Just curious -- has anybody ever tried a usb hub with these mstar boxes? For example - if a portable HD is used as your 'permanent' storage, but occasionally you wanted to access something (videos, photos, music) that was stored on a flash drive. If a hub was connected to the box - and your permanent storage and the occasional flash drive plugged into the hub - would the box see both? None? Was interested when thinking about using a hub to give AC power to a portable drive (I thought I read somewhere that using the box to power a portable drive through usb would increase box failure chances in the future). Perhaps I am in error in that assumption, however. Anyway - that got me thinking about multiple drives connected through a hub and how the box would handle it.
