Some more info: apparently the problem only happens if a DVB-S2 card
(a TT-budget S2 3200 in my case) is (attempted to be) tuned to a DVB-S2
channel after the driver has been freshly loaded. Once the card has
been tuned to a DVB-S channel, subsequent tuning to DVB-S2 channels works fine.

Now I'm unsure whether this is a VDR bug or a driver bug...
