you can dump the stream with dvbstream  using -ps (to save as program 
stream)  then
cut all you don't want using GOPchop,
or you can save as TS with (mplayer -dumpstream) and use lve (which can 
read TS);
only problem: lve seems quite difficult to use; last time I used it it 
reminded me those funny windows programs that
have so many buttons, sliders and menus with all but the most useful 
features (such as cut, copy, paste, save as)
that I ended up quitting the program without any real work done
