You've probably noticed this by now, but once CM stopped using Rovi for guide info, 11 to 12 days has become the new norm. When it's working...

It's gotten a lot like the Windows Media Center guide: 11-12 days, with a lot of outages where it drops below a week.

BTW the WMC is going away completely in January, as it happens. I hope the DVR+ guide doesn't follow suit.

Oh, geez; how stupid!

Looks like that's no longer the case. Every CMTV channel just gives me an "Internet Channel Error" now. And the guide doesn't even show what the channels are, although if you try them the error message lists the channel's title, so the DVR+ still "knows" what they are.

Pandora's still working, so it's not a problem with my Internet connection.

This was expected, of course; and there wasn't much worth watching left on CMTV anyway, but it's still a bit of a disappointment. The colored and "Apps" (Home on the flat remote) buttons on my remote now have no useful function outside the DVR menu.

At least the Internet guide still works. Or does it? Mine only goes out to 5:30 AM on the 13th; hmm, I'd better try a refresh - we may be in real trouble here....
And, the way the firmware is written, you can't even deactivate CMTV now that there's no CMTV server, so I can't even take the now-useless channels off my guide!

I'm going to try a "custom" factory reset to reset only Internet Channel Settings; maybe that will do the trick....

OK; it's rebooting now. Checking the guide....

No joy. Everything's still there, and of course it still doesn't work.

One thing that might work is a full channel rescan. (In the past, that has "unhidden" any Internet channels and/or apps in the process.) But I don't want to do that now.

Guess my only remaining option is to hide every Internet channel individually.

How about install a really old DVR+ version, then 135R? Maybe???

Newbie question here, can I insert a 1TB (or larger) HD into a CM7500GB16? I have a 5 year old CM7500TB1 which I swapped out with a new HD, so I am somewhat familiar with the innards. My question specifically is can I remove or replace the 16GB with 1TB (or larger) HD, leave it in place (soldered or part of the board?) and add the 1TB HD using existing connections, "MacGyver" the HD external to be internal, or best to use the CM7500GB16 as is, purchasing external HD from Fry's or MicroCenter? I am anticipating the WMC changeover, or it being dropped entirely come January 2020 (WMC worked well for about 15 years on a HP Z565) Thanks, Dave

Forgot to mention that I'm looking into purchasing a CM7500GB16 in addition to the one I already have. A 16GB unit is cheaper than a 1TB unit, looking at second hand used prices.

Find my posts with pictures of the 16GB DVR'S main PCBA and read about adding internal HDD to it … should be in first 100 posts part of the thread...

I hope your intention related to SSD not HDD... SSD would be better choice: less power requirement and less heat inside

If it weren't for the Internet program guide, I'd roll back to 114R since I don't have a 4K TV. 114R is a better match for what's still working on the DVR+ (no CMTV, no Sling), I'd get a one-button CC toggle and search (the green button), and I prefer being able to delete unwanted channels over hiding them (given that I can only have one of those choices).

I'd have to relearn how to navigate the (PSIP) guide, since 114R used the other three colored buttons for that function, but I'm sure I could get used to it again.

BTW, it still only goes out to Nov. 20 a day later.

TBH, 11 days isn't that bad. As long as it stays over a week, everything seems fine. But with 11 days, even a 4-day interruption in updates gets us down to the 1-week level, so there's less margin for error.

Thanks P Smith, I found your teardown of the 7500GB16, but as I can decipher from yours and other postings, the board is not outfitted with a direct SATA connection as the 7500TB1 is (a hypothesis, due to lack of side by side comparison). But you mention installing a SSD (I agree, less mentioned issues), so you "almost" indicate that a 2.5 SSD can be installed in a 7500GB16. Without opening up my 7500TB1 (which is online / in use), would I find the same board design? I saw pics of the board with leads to where the HD goes, but terminate where they would connect the HD. Am I wrong about this? Or would I need to solder a HD connector onto the board? My recall of swapping HD's is that the HD rests in a bracket with the HD connector right there (took about 10 minutes, next time less than 5). Is this conversion modification worth my time & efforts, or shall I simply use the USB port with an external HD? Or "pay the piper" for a 7500TB1 when available and go from there? PS: went through the first 40 pages / 1200 posts, finding some valuable info here and there, with transferring CM7500 to Windows the most curious. Albeit rare, would like to save perhaps 5-10 recordings per year ... and now I know it can be done! January 2020 around the corner though, hoping CM7500 is the failsafe way until the "dust settles" with WMC.

Click HERE for P Smith's post with information and photos of the 16GB model guts.

Click HERE for Iowanative's post with photos of the 1TB internal HDD model's guts.

I seem to recall reading somewhere that there are other electronic components that you will need as well. There's also a bracket to hold the HDD in place (click HERE for a sketch and a photo), although you can rig your own. I'm guessing, but @P Smith may know more about what you are trying to do. If you succeed, please describe everything in detail, including photos!

So, does this answer my question? Add these and voila!?
"Four capacitors 10nF, one spare resistor 10K (just for self spinning the drive), SATA combo connector - all SMD; plastic holder"
Don't have these laying around, a trip to Micro Center or Fry's will do if so (Radio Shack now defunct) ... or seek out 7500TB1? Testing my competency in soldering correctly and which goes where!

I have three Channel Master DVRs - two 16-gig units, and one old CM7000PAL. I have previously run them all entirely over the air, with tremendous success. I still run them OTA, but this past week added Ethernet cables to all three. On the two 16-gig units, the streaming channels work fine - I watched a Vudu program on each as a test. But the Rovi guide and the CM internet channels didn’t work.

I logged a ticket with CM customer support. Of course they told me that the internet channels no longer exist, and advised they could help me get them out of my list. My list is empty, so that’s not an issue.

They said the OTA guide provider is doing maintenance, and they hope that will be done by the morning of 11/13, at which time the OTA guide should download to my units.

Of course the CM7000PAL would only use it’s new internet connection for guide information, since that model has never had a software upgrade, and doesn’t do streaming channels like Vudu.

Thanks pachinko, I placed Iowanative pics and davezats / P Smith's pics side x side in two different Windows, leading me to believe each the 7500GB16 & 7500TB1 boards are the same, however, the TB1 has the HD connection right there along with the mounting bracket. Using KISS theory & inadequate knowledge of parameters Channel Master uses, I'm better off finding a used 7500TB1 than to attempt such a procedure as I intended. Still, it looks possible, but why chance it for a few bucks. Thanks everybody for your inputs!

If you have never had them connected to the Internet before, make sure you have the latest and final firmware upgrade installed on all your DVR+ units. It's v135R, and the Internet guide--no longer Rovi, won't work with any other FW version.

Sorry to bring ATSC 3.0 format to the board, but it appears that 3.0 will render ALL CM tuning devices (and all others) obsolete once implemented. My take on this is once OTA broadcasting is changed over from 1.0 to 3.0, broadcasters will have 5 years transmitting both 1.0 & 3.0, then we'll need tv's & recorders that have new 3.0 tuners, as 3.0 is not backward compatible with 1.0, what is used today. So much for my hunt of a 2nd CM7500TB1 if the tuners go obsolete. 4K is on the way, with 8K not far behind ... that's progress / every age has it's era (another reason to be glad I'm old, I've seen enough!).

Thanks. When I try to do a software upgrade, it says Unable to download, Unknown error, Latest software detected. But when I check Version info, it is 134R (0.5). How do I get 135R downloaded?

I reported this error to Channel Master Customer Support, and they said it only means that the latest software version is installed. But we didn’t discuss specific version information.

However, you referred to “firmware”. Would there be a different process to updating firmware than software?

DVR+ Dies When Scrolling Channel Guide

Recently my DVR+ is exhibiting some strange behavior. When watching live TV and scrolling the channel guide a line at a time or a page at a time, the TV screen will go blank gray with no audio and the DVR+ is completely unresponsive to the flat remote. This had not happened when playing back any recordings.

I have tried both a warm boot and a cold boot and the problem still occurs. The only change I have made in recent months is that I moved the unit from one room to another. In the new location there is no wired internet connection so I installed the Channel Master wi-fi adapter that came with my unit when I first purchased it.

For my next step, I plan to:
..unplug the DVR+ power
..disconnect the external hard drive
..disconnect the wi-fi adapter
..repower the DVR+
..perform a default factory reset
..reinstall the external hard drive
..reinstall the wi-fi adapter


If that does not work, I suppose the next step is to replace the external hard drive. I seem to recall some comments that a hard drive going bad will cause the DVR+ to lock up. The hard drive is a Toshiba unit (a model recommended by Channel Master) that is now about five years old. It may have reached its end of life.

Any other thoughts?

Let me tell you what I learned the hard way about external hard drives on Channel Master DVR’s. Many of you probably already know this, but for the sake of those who may not...

No matter what brand of hard drive you purchase, there are two ways they can “fill up”.

Obviously they can get to 100% on used space.

But they can also max out on number of files. My testing and research indicate that that number is roughly one thousand files. Once I discovered that, I found out all of the old drives I thought had gone bad, are now suddenly reusable again. I have used Seagate, Western Digital, and of course the fan favorite Toshiba (both the 1TB an 2TB varieties). The way around this problem is to double up on recordings. If I want to record several shows in a row, I do a manual recording to get them all into one file, and then rename it to something descriptive.

Prior to discovering the above, all of my drives would get to somewhere between 40% and 60% full, after which all recordings would error out. No longer could you write anything to the drive, but you could still watch what had been previously recorded, and could delete previous recordings. I have since deleted a lot of little files from them. I am now recording big (longer in time) files, and consequently I am able to make the percent full rise above where it had previously maxed out.

Hard to get to 1000 on a 1TB if all you tape is 30 & 60 minute shows...

The title says it all - your experience got me curious as to how close I am to that ~1000 file limit.
The answer: The way I record, and with my 1TB drive, I'll never get near that limit.

I am currently at 95% capacity, about normal for me.

My list of recordings is 144 lines long (~18 screens @ 8 lines/screen).
When I add up the number of recordings on all the lines that have multiple recordings, I get 379.
Added to 144=523 recordings total (actually less than that, since I am double-counting each line that has multiple recordings).
So I am a long ways to 1000 recordings, and the way I use the 1TB drive on my DVR+, I'll never even get close.

That's because 99% of my recordings are 30 and 60 minute shows.

And if you record longer shows, like Ken Burn's documentaries, sports and/or award ceremonies, your recording count will be even smaller!
So, I'm assuming that this recording limit is only an issue with 2TB drives.

(Unless you are very fond of recording 2-reel Three Stooges shorts.)

You can download all the versions using the link in this post:

Previous DVR+ FW versions

Use a flash drive formatted as FAT, not NTFS. Make sure the FW file is in the root directory. Disconnect any external hard drives or dongles that are plugged into the USB ports. I don't remember if you plug the flash drive in then power up the DVR+, or if you can plug it in while it is already on. Once it starts, it's all pretty hands off until it finishes.

Sorry your just now discovering this as it's been known, and mentioned, for many years. The limit is actually 999 as that's all the slots provided in the DVR+'s REI file (the file size is always the same size of 868,024 bytes). There's actually 1000 slots but the software does not use the 1st slot (no strm0000 files).

There is another limit that determines the maximum number of allowed Scheduled Recordings, and that is 54 (some think it's 55 but it's not, it's 54).

I've seen the "strm0000" files on the HDD at PC screen when disconnect DVR from power during recording, after rebooting DVR with the drive the files never seen.
As to reaching file limit [999] related to number of recordings, DVR recording long show by chunks [2GB ?] so one long 1080i show with high bitrate could produce many files ...

Looks like my DVR+ will no longer pass sound. Checked all the usual suspects - HDMI cable, HDMI port in TV, DVR+ settings (both the "stereo" and the more advanced audio setting), TV, antenna connections, and coax connection into the DVR+. reset, etc.

So much for my hunt of a 2nd CM7500TB1 if the tuners go obsolete. 4K is on the way, with 8K not far behind ... that's progress / every age has it's era (another reason to be glad I'm old, I've seen enough!).

It's come up before. At this point the consensus seems to be that ATSC 1.0 isn't going away anytime soon. We probably have much longer than five years; that's just the minimum the FCC is guaranteeing.

There are a number of obstacles to widespread adoption of ATSC 3.0, including the lack of an FCC mandate for either stations or tuners (IOW, it's purely voluntary), competing technologies such as 5G, the lack of spectrum with which to make the transition, and the likely adoption of "digital rights management" schemes that will raise prices, narrow choices, and generally make ATSC 3.0 less attractive. (Who would want a DVR that couldn't skip commercials? Might as well just stream the content on demand.)

I used to be pretty worried about it, but now I believe ATSC 3.0 will "succeed" only as a niche market, a la HD radio. I'm following the development of the technology, but not letting worries about ATSC 3.0 stop me from buying ATSC 1.0 equipment.

I've seen it too - my guess is that entry 0000 is used for buffering the channel being watched, so buffering still works even if you have all 999 recordings in use.

Ouch. I suppose the one remaining possibility would be using the DVR+'s optical audio output. You'd need an optical cable and an AVR that could accept it, but that still could be cheaper than replacing the DVR+.
