Did you grab one of the newer versions of dvbstream which has built in ts2ps
functionality?  I think this will probably be needed to avoid an external
dependency when grabbing the video stream?

For anyone following this at home, there also appears also to be a fairly
big synchronisation bug with the 1.00 pre1 and pre2 linux DVB driver when
grabbing the demuxed mpeg stream.  There is a small patch on the VDR mailing
list, title "A/V sync problems with new drivers,", or I can send it if
anyone can't find it (haven't tested it myself, but I've found the sync
problem!)
