Hmmm, that's akward. This is actually not too bad of a mainboard 
(Gigabyte GA-G33-DS3R, Intel G33 chipset - combined with an Intel Core 2 
Duo E6550 - CentOS 5 64-bit). Seems like the card is sometimes 
struggling to get the data across the pci bus, but I only record SD, 
which is between 5 and 8 Mbit/s (depends on channel). That shouldn't be 
a problem.
The capture card could be a problem - got it through E-bay :)

Kind regards,
