What I did a couple months ago: 1) Ripped Ratatouille BD 2) Joined the main movie files using tssplitter 3) Used tsremux to keep only the video and dolby digital streams 4) Burned the file to a BD-RE as a data disc-played it several times in my PS3 without problems Today: 1) Put in my backup data BD-RE of Ratatouille in my PS3 and audio and video were out of sync and vido was studdering. 2) Tried streaming the file to my PS3 from my PC-same result as with the BD-RE backup 3) Tried streaming the file to my Tvix 6500-same result 4) Re-ripped the movie from the original and used tssplitter to join the main files, and used tsremux to keep only the video and DD audio streams. 5) Was able to stream to both the PS3 and to my Tvix without any problems Does anyone have any idea what might have happened to this file on my BD-RE? I did recently update my PS3 to 2.10, but I don't see how that could have corrupted the file on the disc in any way? Does anyone have any ideas? Thanks in advance.
