Since TVGOS went away about a month ago and I started using PSIP, I constantly see the detailed program descriptions come and go, randomly. Sometimes, the info will be there when I first land on a time slot, then disappear while I'm reading it. Other times, it will show "No information" and then fill in with all the detail after a few seconds. More frequently, however, it will just remain "No information" with only the title displayed.
I have checked several times and my Sanyo TV will have detailed program descriptions where the CM-7000PAL only has the program titles. So, the problem may be with the DVR's ability to translate the incoming data. On the plus side the CM-7000PAL displays several days of PSIP when it is being broadcast (about half of my locals), while the TV maxes out at 12 hours.
Extended descriptions are sent in a different part of PSIP (Extended Text Tables or ETTs for short) than the "main" part of the guide (Event Information Tables or EITs). Station equipment often sends the ETTs less frequently than the EITs, so it's likely that the Pal doesn't "stay tuned" to any single station long enough to pick up all the ETTs it broadcasts. The Pal seems to be good at merging new EIT data with its existing guide data, but not so much with ETT data. So it picks up some descriptions and not others, depending on what each station happens to be sending when the Pal scans through the channels and updates its guide.
There's probably not much you can do about this, other than switching to another DVR that gets guide info from an Internet subscription. For OTA viewers, the only options are: 1) A TiVo Premiere: cheap, but the subscription is rather expensive and mandatory (that's how TiVo keeps the boxes cheap). 2) Channel Master's other DVR, the CM-7400, offers a reasonably-priced Internet guide; but it's reported to have overheating issues and a rather poor tuner. 3) A PC with appropriate software (such as Windows 7 Media Center, or Linux + XBMC) and hardware (such as a tuner card) can serve as a DVR with a good guide (WMC's guide is free, and XBMC's is very cheap), but you need some PC knowledge.
All things considered, you may be better off sticking with the Pal DVR, even with its quirks.
