I've noticed that while watching a DVR'd title, when the picture breaks up due to a weakened antenna signal, often when the signal returns the audio keeps playing just fine, and then it takes several seconds for the picture to catch up. Then when the picture starts playing again, it plays super fast until it catches up with the audio. All of these fast forwarded frames appear completely clear. So shouldn't all of those frames have been able to play alongside the audio just fine, instead of with a delay and than catching up with fast video? This fast-forward motion always results in a comical effect where other people are moving their lips while others are talking and everything moving quickly, lol, but yeah of course I'd prefer everything to be in sync and at the correct speed.
For reference I'm watching on a Sony x930d TV.
