it seems so... I just applied both patches and the dvbtuner
patch also here improves switching times quite a lot and I use a
fullfeatured dvb-c card + a budget dvb-t one (which is what needed to be
tested as far as I understood the author who only has a single ff-dvb-s
card)

I currently have more problems when watching recordings and fast forward /
dealing with marks. It can take up to ~10 seconds before anything happens.
I used to get vdr hangs (had to kill vdr + reload dvb-ttpci module) in the
BlitBitmap() OSD call but michael hunoldt + me seem to have fixed that in
latest dvb-kernel cvs-driver (well it timeouts now - cause is still
unknown).

Soeren.
