Ricardo, thanks for you input. I tried this out tonight and found
that it really did not help. Let me tell you what I did so I make
sure this is what you ment.
Aug 22 21:54:12 samwise kernel: ivtv0 warning: 1000 ms time out
waiting for firmware

I did not recompile the kernel, howver, I did $ chkconfig irqbalance off
I am not sure if the card is sharing an irq. When I look at
/proc/interefupts here is what I see.

My 250GB hard disk gets here tomorrow so I will be loading FC4 x86 and
x86_64 to do some testing. I might also try FC5 x86 as well like Tim
mentioned.
Thanks for your help. This was a really good idea to try.
