did you notice any improvement? what dvb hw?

Not in this form, i hope :) I'm still trying to improve it a bit; i'll have
to test a few other changes, but that requires watching tv for some time, 
which i don't have right now.. I'll try posting another patch in a few days.

BTW, the reason i said it brings the speed _almost_ back, was because, while
usually tuning was relatively quick, sometimes it took seconds, and in 2.6
and/or dvb-kernel the "slow" channel switches seemed more frequent.
This seems to fix it:
