Hi I have backed up my bluray discs using DVdFAB and have tried playing the .m2ts video files on the ps3, the video works fine but there is no sound what so ever. When i play the files on my pc using VLC however the files play perfectly with sound. I dont know what has happened and why the ps3 wont output any sound. can anyone help. Is there a setting in the ps3 i need to change to get sound.
