Will do. Question though.
This file was a recording. Named "1023_20080311101559.mpg"
Can I just choose transcode on it and do the same thing? Perhaps I
should transcode all files after recording?
I am wondering what a permanent fix could be. This came from a TV
recoding originally.
Or do I need to run another transcode command?
Thanks for the help. What is the root cause of this problem though?
ffmpeg or something else?
