Not sure, its a remote frontend, all commercial flagging usually gets done 
elsewhere. I'm guessing it would be slightly unhappy while working on 1080i 
streams, not sure about 720p. I seem to recall my 3200 getting a bit choppy 
on the large info OSD fade (Titivillus theme) when playing 1080i recordings 
and commercial cutting at the same time.

avidemux says the 720p recording I'm playing with right now is 59.940fps, 
couldn't be absolutely certain that's the case with all of them.
