I believe you have found the problem, but I don't know what the solution is.
A bttv card's channel tuner is typically controlled via the i2c bus. So if
that module is not installing properly, as the error message you saw, and
several others near it, seems to indicate, then the card most likely cannot
be tuned. I also note that the bttv module is ID'ing the card as type=0,
not as the type=2 that the CARDLIST file associates with older (bt848)
Hauppauge cards. You may need to specify by hand the card type and the
tuner type by hand (as module arguments) to force recognition of this card
(see the kernel-source docs in (something like)
/usr/src/linux/Documentation/video4linux/bttv for the details).
I am insufficiently familiar with Windows even to know what it means to
"change my PCI latency on my windows box".
I doubt the IRQ sharing is a problem. If it is, you can try running
"irqtune" to correct any conflict.
Perhaps someone else more hardware savvy than I can offer a more focused
