Hello,

When playing this [.mkv] file it starts off fine then loses audio synch.

This is being played through SamsungB-[DLNA]Smansung LN52B750, and SONY-STR-Sony DA4600ES. Connections are hard wired from the computer to the components through a Zyxel 8 port switch.
The computer is running Windows 7 Pro -w- i7-2600K CPU with 16GB of DDR3 RAM@1333Mhz
-------------------------------------------------------------
I have tried transcoding the file using
1. mpgets -> h264 video; ac3 audio fur just the SamsungB component
2. mpeg (PAL) -> mpeg2 video ac3 audio for both the SamsunB and Sony STR components

Also I just thought I'd mention that VLC 2.0.2 also has problems playing this file on my computer.

Thanks

Joe
