This is happening with the mpeg2 decoder with DVB also.  A new buggette also appeared recently where if you set a chop point to remove say the adverts before the start of a program, then quit and re-run the program the chop point appears to have moved forward in time about 5+ secs, and now you get about 5 secs or so of adverts before the prog starts.  Seems that something similar is happening with cut points.  (Note this is with the old position map code, not the new code using frame numbers)
