Marking commercials and marking cutpoints are two different things.  You 
turn on commcercial flagging in the setup section of the frontend.

The "m" key lets you mark cut points (sections to be skipped over during 
playback / transcode).  You can load your automagicly marked commercials 
as cutpoints, tweak them and what not.  Pressing the space bar while in 
this edit mode allows you to mark a point as a cut point.  You block out 
sections by creating high/low water marks of "Delete after this frame" / 
"delete before this frame" cutpoints.

If you press "X" during playback it will mark the file to be 
transcodeded to MPEG4 (in your case).  Anything marked with the cutlist 
will be removed from the transcoded file.

Right now there's no good way to transcode from MPEG2 to MPEG2 and 
remove commercials.  There's some rough code in CVS but it was some 
issues that need resolved before it's usable.  (Which is one of the 
reasons I've not finished the DVD modules yet)
