hello..

I have several movies in mkv format with AC3 sound. that need to be transcoded. but with the ps3 media server I can play without transcoding. other movies with dts sound be played without transcoding. can you tell me why this is so? I have a sony x9005b TV. ac3 is yet to be no problem for this tv?!

This movie needs to be transcoded:
