I wish I knew how to create this problem, then I may be able to fix it. 
In my case, watching Live TV occasionally gives a short pause or two in 
the audio in the first 5 seconds or so, then is fine. The short pause 
that I do get, results in the recording catching up to the playback in 
case it is slightly behind.

I will look at it under ticket
Perhaps that pause is not actually working the way I assume. It could be 
that your signal has a bigger than usual audio and video offset and the 
playback is never rectifying itself.
