Thank you for your inputs. I never use dolby  digital because I use
stereo speakers on the TV. Even if I disable dolby digital in the DVB
configuration I still get the problems. Somtimes high bitrate channels
works after switching to the DVB-T card and then back again and with
your information I can force the problem to come back even if channel
works without problem. By changing to dolby digital audio instead of
stereo the channel becomes bad again and remote is barely responsive.


My configuration is:
Gentoo linux with Athlon64 3500+ CPU compiled for 64 bit with Hauppauge
version 2.1 DVB-S and one Airstar2 DVB-T.
I have the same here 04:07.0 Multimedia controller: Philips
Semiconductors SAA7146 (rev 01)
