As I said, I work on upgradeing avlibs in Cinelerra. This means all 
encoding/decoding will be replaced with new libraries. Testing and 
reporting encoding/decoding errors at the current state is unimportant.

About your problem. Just quessing.

A video file consists encoded audio and video stream that are muxed into 
container. There are standards what encodings can be put into a 
container. The current CVO can put any encoding that is possible into 
container. Newer ffmpeg and mplayer understand only allowed by standard 

Cimelerra calls containers formats.

If anyone wants to help - CVE needs testing. Encoding and decoding there 
is mostly this, that will be some day in CVO.
