I get this problem when I try to insert a m2v file into a project:

"COULD NOT INTIALIZE DECODER''
(its a pop-up window)

In case you need to know the m2v file(6Gb) was demuxed from 8 vob files with VOBEdit. It has had trouble with m2v files in the past, but I don't know if they are the reason.

What do I do now?
