yepp, I did not try that simply for it seems to depend
on overriding/replacing a few modules in the 2.4 kernel
and it happens that I do have a bttv card as well.

As of late, however, I learned that linux >= 2.4.19 has
a V4L2 layer and all calls to V4L1 are mapped to the
new api. What do you think, should it be possible to
compile dvb-kernel drivers for linux >= 2.4.19 _without_
replacing some of the original modules? IIRC, distros
ship with kernel >= 2.4.19 for many moons now, so...

cheers,
