And more question for you guys. My cm 7400 has massive audio video delay.. Sometimes it's just one channel and the rest are fine and sometimes it's every channel and its really bad. Anyone else having this same experience? Any ideas on how to fix it?
post #1892 of 1996
See last months posts here - what was tested and working; WDC AV-GP are pretty good drives.

Since it's just the dock you also need a Hard Drive Disk correct? Any recommendations for which one to buy or does that not matter as much as the dock?

I think any SATA drive will do. I used a Seagate 2 TB and it worked fine. I would actually recommend disconnecting the internal drive to reduce heat inside the unit. It's not really difficult to take the screws out and lift the top up from the back just enough to get there and disconnect the power and sata cable from the internal drive.

I heard others have to change the channels to get all of the the psip updates. On my 7400, when I plug in the unit (I do this to save energy) it will start to update the psip on all the channels without me changing to them. I leave it on the channel it comes up with. I haven't tested it to see I leave it on, will it still update the other channels.

I tune QAM (Cox Cable) channels with my 7400 and use CM's Premium Program Guide. Most of the remaining ongoing problems I have are temporarily cured by Restarting the unit daily, sometimes twice daily. Menu / Settings / Restart & Reset / Restart, or press and hold the Power button until you see the Channel Master overlay. I suspect this may also solve the Basic Guide info updating issue as well as when you individually tune each channel. "Reset to Factory Default" is only required for serious problems, for which you'll lose all saved recordings and have to completely redo your channel scan and setup.

After a year of ownership, it would appear that folks tuning OTA channels have far fewer problems than those like me who tune cable channels. I imagine this might be because the 7400 just doesn't have a powerful enough CPU to handle the rigors of processing HD data feeds plus manipulating the data load of the PPG plus everything else it's being asked to do.

I turned in on in the morning, brought up the guide and watch the channels populate. I turned it off but kept it plugged in. This evening I turned it on, brought up the guide, and it was at that point that it started populating the channels again.

So manual recording is the only safe way to go for this machine. At least with my testing.

After ONLY two years my Channel Master CM 7000 Pal stopped feeding signals to my HD TV. The lights on the front both light but no images are shown on the TV screen. Interestingly, the 7000Pal still transmits viewable signals through a Slingbox 500 to my wife's iPad

I am looking for advice. Can/should I get the 7000 PAL repaired, if possible or go to a new and different unit? What would you all recommended? I used the unit exclusively to capture OTA signals. I have Direct TV for the other stuff.

I am really upset that the unit stopped working after only two years of use!

Your thoughts?

Perhaps move the post to appropriate thread ? wink.gif To DTVpal DVR
post #1900 of 1996
The CM-7000Pal has a much better tuner than the CM-7400. So I would not recommend it as a replacement. There are some identical Dish DTVPal branded versions now available from Antenna Logic seller as discussed in that thread, and it has a better tuner and is an overall better performer. But sounds like from your updated post you corrected a mistake and got your Channel Master version working again.

Have you tried unplugging it overnight?

So hopefully if their is a new batch it will include the updated version with the cooling fan. And would be nice if it has a better tuner. And they have also been out of their new CM-7777 preamp, but are supposedly awaiting a new supply. They truly need to do a better job of maintaining inventory of their major products.

AntennaLogic has two listings for the CM-7400: One at $429.99 and one at $460.00. Edit: The $429.99 is a return, but claimed to be fully functional.

I ended up going with the Thermaltake BlacX and a Seagate HDD. I hooked up everything just as you recommended however it doesn't appear as though the CM 7400 is recognizing the drive. My old recordings shouldn't still be showing up should they? Any advice?

confused.gif hope that recommendation was about eSATA connection, not USB ... [see my post#1007]
post #1908 of 1996
Yes this is hooked up through eSata.
post #1909 of 1996
eSATA ...

check the eSATA cable by connecting to PC or replace it
post #1910 of 1996
eSata cable appears to be working fine. Hooked up to pc and worked just fine. Any other suggestions?
post #1911 of 1996
eSATA

Need to power the drive first, then STB

I don't know if it matters for sure, but on mine I disconnected the internal drive before using the external drive. For me, the external drive is working great.
post #1913 of 1996
Thanks. I'll try that. Do you have a good explanation on how to do that or can you direct me to a previous post that explains it? Thanks again!
post #1914 of 1996
Actually when I connect it to my computer it makes a noise as though it recognizes it, but it doesn't populate in the "my computer" folder. I would've thought it wou would show as an E: drive or something but nothing. Very confused.

it shouldn't - see post 1007 and around about the type of file system

From my memory, there are screws that hold the top cover on. Then you can tilt the cover up from the rear and reach in to disconnect the power cable and data cable from the drive. Then just put the cover down and put the screws back in and you should be good to go.

I'm waiting ...


After a few minutes waiting:

- Connecting to Network...

- Loading channel master TV...


Got Setup first screen, taking a break, checking file system after formatting the 1.5 GB ... Shows 225 HD hours recording time.


Formatted, created as one EXT3 partition, but there is a catch - not conformed/tainted file system, regular program like UFS Explorer cannot read it, only other forensic tool can got to the folder/files ...


Folders/files are the same what I saw on factory HDD.

One folder name [amuletg1-xxxxxxxx] tell me the box has a codename AMULET.


Oh man ! I did finish initial setup of the box - they are start from shows our local ch1.1 what just plain TVGuide VIDEO channel.

Getting PSIP (no network yet, purposely) and the box got correct local time; best GUIDE from ch5.1 KPIX - up to 7:00pm Tue 2/14


Found 86 channels ... Lets see what TR-50 will got from same antenna... - 85 services; so it's on same sensitivity level. If you want to see how the scan stored - check second ZIP file.


Wrote small piece of PGA tour ... Got the drive out, there is boring log (attached).


For the recording it created sub-folder "tunera-0-8vsb_563000000_1-000016lpot6gl" under factory "amuletg1-xxxxxxxxx/asset/"; there are a lot of files (pointing to freq 563 MHz):

.pmt

.tsinfo

drm

nav

rai

0.ts .... 12.ts (that is TS files, each 50 MB max !)

tunera-0-8vsb_563000000_1-000016lpot6gl.info


Next events recorded into same folder "amuletg1-xxxxxxxxx/asset/" under different sub-folder (similar) names:

tunera-1-8vsb_587000000_3-000016lpu1a76

tunera-1-8vsb_641000000_1-000016lptetgd

tunera-0-8vsb_563000000_1-000016lpsqmsc

tunera-1-8vsb_641000000_1-000016lpt46fl

...



Next test: moved the 1.5 TB to BlacX dock connected thru eSATA cable to CM7400; booted OK, everything is fine, last recorded event is here and playable.


Two drives test: 1.5 TB as internal, 250 GB in BlacX. Result is negative - second drive left intact, side effect when it spin down by internal controller (?) the CM7400 did reboot, still using 1.5TB drive.

Honestly I don't understand even a quarter of this post however a couple things stand out. Do i need do a factory reset?? and do i need to format the HDD??

I didn't factory reset, I didn't format that drive

I tried to eliminate all but the important parts. Looks like P Smith first connected his new drive internally. The CM-7400 formatted the drive and reset itself to factory defaults automatically.

Then he moved it externally. The drive still worked.

Finally, he moved it back internally and connected a second drive externally. This time the CM-7400 used the internal drive and ignored the external drive, which sounds like what you're experiencing.

Conclusion: you need to disconnect the internal drive for the CM-7400 to recognize an external drive, but it should automatically format the new drive for you.

I love you guys. THANK YOU SOOO MUCH TO EVERYONE INCLUDING P SMITH, JHBRANDT, and PCNETWRX. After opening up the CM 7400 and disconnecting the esata wire and power cord from it's hard drive I then connected the thermaltake externally and everything is working flawlessly.

Last 2 questions from me:

When I booted it back up it said restoring to factory settings. Can I safely assume I lost all my original recordings on the CM 7400's internal hard drive?

The CM 7400 is still running just as hot as it was before. I thought disconnecting the internal hard drive was supposed to cool it off?
