On my digital juice HD jumpback DVD - the movie format is PNG.
This is a still image format -
not a very useful format for playing back.
not sure why you just expect this stuff to work - it doesnt.
I do the best i possibly can with whats available.
You can even do uncompressed video if you can get 200MB/s second from a raid system - but you cant get 200MB/s from a single scsi disc.
