Audio delay in new x264 TV Rips on Bravia 2010

Hi all,
I'm just curious to see if anyone else is having issues with the new x264 format TV shows that are coming out these days playing on the Bravia's.
It starts out ok, but within a couple of minutes the audio gradually starts to go out of sync. If I stop and restart it then 'resyncs', but after a few more minutes it gradually goes out of sync again.
Another issue I have with both AVIs and x264 and that is pausing. When I hit pause and then unpause, it doesn't start from the same place. It starts from usually about a minute or so ahead.
It's worth noting that on the same network I have a PS3 that has no issues at all using the same server.
Cheers
