Film with DTS audio sound problems on playback

Hi,

I've just purchased Mezzmo and am in the process of trying various things. I've got some Blueray rips with DTS audio and thought I would let Mezzmo transcode it for me. However, when I start the film the audio almost immediately becomes out of sync with the video. The film position marker seems to skip forward to 17mins as soon as the film starts and then rapidly continues through the film even though the credits are still rolling!

I've converted the DTS to AC3 using Popcorn MKV Converter and it now plays perfectly (no transcoding). I have a Samsung LE40B650T2W for which I use Samsung B profile.
