I promise it has nothing to do with that.
My trouble with my local PBS-HD goes way back - a couple TVs and a couple recorders back. Thanks for the thought, though.
Yes, I am familiar with the DST problem and fix on other units.
The 797 never had any problem getting and keeping the time, or with dropping channel lineups like the other new recorders.
Here is the short version:
A while back my local PBS changed their broadcast of PBS-HD from constant to variable bit rate. My (then) Philips TV then could no longer process the signal - garbage picture.
NB: Only one subchannel was now bad, so it's not a reception or antenna problem. It is the actual format of the broadcast. There are 18 ATSC formats, and I don't know if some tuners have trouble with some of them or what. I think so because some tuners have no problem with the same subchannel.
A firmware update from Philips fixed that problem but caused others. I ditched the Philips for an LG. The LG TV receives the signal fine. The LG recorder however could not. I explained this to LG, so they also could not simply blame the station. Soon my 30 day return window was closing with no sign of progress on their part, so I returned the 797 to try others. I am still monitoring LG's website. If I see signs of them acknowledging and fixing the problem, I would probably re-buy it.
