I'l reiterate that MPEG2 is probably the least desirable format to 
archive video in, if future editing is a consideration. For one thing, 
because it is temporally compressed, it no longer contains discreet 
frames of video. While some software solutions exist which will 
reassemble frames suitable for editing from you can never actually get 
back what has been discarded in the initial compression process. MPEG2 
is a final distribution format, and is not considered an archival format 
for source media.

Additionally, I know of no way for the DVD format to be decoded inside 
the Rev environment, and doubt that we will see one.
