bttv is by no means better hardware. The difference is basically the 
bttv cards create uncompressed video and rely on the processor to handle 
it, whereas the ivtv cards do all the compression in hardware so they 
don't require much of a cpu. The ivtv cards are probably more expensive, 
so if you have one, keep it. If you really don't think you are going to 
get the ivtv card to work, you can pay probably $50 for a bttv card, 
like the Ati TV Wonder (my card), but there must be some people using 
ivtv and mandrake successfully.

You might download .15. Its not going to solve your problem, but it is 
newer.

So you're probably right that your kernel modules aren't set up.

Like I said, I haven't tried anything dealing with ivtv. If it requires 
2.4, that's what it requires...

This is the line I would expect helpful info on. Right after this -o 
line. If you made a file out of these errors, you could probably post 
the file assuming its not too big. If there is an ivtv mailing list out 
there somewhere, you might want to join that.

Usually this specific type of error is due to a bigger error like a 
missing file.

This list has supported me, so I'm willing to try to support others. 
However, I know nothing about ivtv, which is where your problem seems to 
be.


Ok, so maybe ivtv does not support kernel 2.6. Some things do not. 
Mandrake 10 ships with a 2.4 series kernel rpm along with the 2.6 one. 
So install kernel 2.4.*.rpm and kernel-source-2.4.*.rpm. Boot into that 
and try compiling again from there. Otherwise, check for ivtv 
information (known problems, mailing list, etc.). Or hopefully someone 
who's compiled ivtv on this list (especially with Mandrake) will chime 
in with suggestions.
