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?
