[mythtvnz] VDPAU AV-Sync Errors

[Steven Ellis]

Well I've been testing the latest builds and for the most part stability
is greatly improved on the VDPAU support for freeview|HD.

I did have a reproducible issue with Maori TV and Parliament this morning
when they are displaying their testcard with an audio stream. Samples are
available at

These play without issue in a recent build of mplayer but if I use MythTV
I get the following output and start to get jumpy playback

I'd appreciate it if anyone could grab these samples and try them on their
Myth environment to make sure it isn't a configuration issue. The sample
files are around 3.5 MB each.
