There is an option to cut video that is already in mpeg2 format and  
leave it in mpeg2 format without transcoding the video. I've never  
used this feature so I'm not sure what the settings are. I'm sure if  
you poke around on the mailing list or in the wiki you can locate it  
there. Basically, you would make sure your commercial flags are set  
to the right places, cut them out without transcoding video, then do  
not transcode video when burning your DVD with MythArchive.
