Hi, cheers for all your help so far. If you are sure they were patching the kernel and hence the extra options I am happy to draw a line under that line of investigation.. as i wondered if i was using the wrong kernel or something.

Secondly I dont really understand the commands you have given me there. I have my 3 kernels yes at /usr/src with a symlink pointing to my active one which DOESN'T have any DVB stuff compiled in at all. I got the latest gentoo-sources kernel to experiment with and ultimately to switch over to, booted into it.. and downloaded the v4l using mercurial did the make install and it all worked grandly. but how do i know where it has put its modules, if it puts them under /usr/src/linux or gets any kernal info from there then they are in the wrong place. But if it is clever enough to know what kernel i am currently booted into and put them in the correct place accordingly then I am still stumped as i cant get this blasted card to work.

Can you also recommend some kernel debug options i can turn on? Can they be done as parameters to the kernel instead of compiled in? i have plug and play debug and some USB debug but i'd like more!

Thanks for your help.
