he tried that now and the result is a bit surprising. While he couldn't
see anything, neither with czap nor with vdr, vdr managed to sample the
epg of all free channels. But he couldn't even see the on screen menue
and a recording, he started blindly, doesn't contain usable data. But
ist does contain data, so vdr got something from the driver.

This is the output of insmod and czap
