Hi all, I've checked in here occasionally, though never posted my symptoms, as they were covered by everyone else.
Dropouts only on 24fps material (recordings, never watched any live), sometimes accompanied by about a 10 second jump forward (had to skip back once) or a freeze (had to rewind maybe 30 seconds, since it went that much ahead while frozen). I think those 2 things were [mostly] only on the NBC/CBS channels (5/4) though.
Well, sometime between Monday night and Tuesday morning, it seems that our HD locals got new MPEG-4 encoders, as recordings are taking a lot less space since then (my AVS Forum post #8964, item 2).
Awhile after I played Knight Rider from Wed., I began to think I couldn't remember hearing audio dropouts during it (though the local channel is not passing 5.1 now, so figured that might be related, but it's not). Then last night I played Eleventh Hour from CBS and its audio was flawless
, which has never happened before! (AVS Forum post #8966)
Now since then I played a little bit of the second half of Terminator: Sarah Connor Chronicles (first half was OTA because of conflict), and it was also fine -- I'm sure I also had drops on Fox shows. And just now checked the beginning of Life on Mars on ABC, which was glitch-free.
So each channel/network seems to be doing well!
Did any other markets notice smaller recordings suggesting new encoders?
I would assume some newer markets have had the same types of encoders as national channels (more efficient) all along. I don't know which or how many DMAs had this problem, but maybe that's what they have in common.
