The problems I was seeing was with just catting /dev/video0 to a file,
and it would hang immediately with several DMA errors (and a zero length
file).  I wasn't even running myth yet.  Since that time I have run it
in PIO mode under myth and it seems to be ok (albeit with 30% CPU).  The
interesting thing is that last night I updated to the 0.10.3 package
from gentoo (I had 0.10.3 from source on the system previously) and I
found I had "optimize for size" (which I read caused someone issues with
ivtv) set in the kernel config, which is something I usually don't do. 
So, I recompiled the kernel without "optimize for size" and then updated
to the 0.10.3 package, and viola, it now seems to work fine - no DMA
issues.....  So I am happy, but also surprised.

Thanks for the tip,

Rett Walters
