pabeader did an antenna removal to break his timers so he could see the channel changing bug.
If the drift is tied to the temporary fix of leaving the box on, then it shouldn't be the same problem once people get version 103. It could be a problem, if people are away from CBS for long periods of time while their box is on, and their area stations are not good about PSIP timekeeping.
My set was on a lot yesterday, while I was playing with the new toy, and it did not get hot. It's as warm on the bottom as the CM7000 is on the top, but not hot.
From reading trp2525's report, if time of day defaults to the non-CBS channel it's on, then I won't see any problems, since my stations are all doing a great job of time keeping. I'd have to wait until a station's time is different before I can see if my timer drifts. CBS was off the air today, so if the time defaulted to another station, I'd still be in perfect time, as I was.
Thanks everyone, for helping me see the background for this drifting problem. It does not sound like it will be a problem for me, since I have the inactivity timer engaged, and if time ever defaults to a non-CBS station, it will likely be the same time. Cheers to the Portland station engineers!!
