I have Prolink Play TV Pro and I has the same proble. You must recompile
your mplayer with:
./configure --disable-tv-v4l2 --enable-tv-v4l
Mayby your bttv is not 2nd version or you have only version 1. Mplayers
./configure misunderstends a bttv version on Debian Sid (in Woody works
with the same 2.4.18 kernel... strange).
