My guru buddy had alll kinds of problems capturing with the Canopus
ADVC-100, slow recognition, lost frames, constant restarting ADVC-100, XP suddenly rebooting, sound dropouts, black frames, etc. He ran a special software to check the computer and it said it was ok. Everything else seemed to be working ok. Finally checking the details on one of the XP reboots it had a lot of memory addresses involved so he went into the CMOS and found the memory was in manual at the correct setting. (DDR 400 Elixer) (Gigabyte Board) He put the memory in auto and everything cleared up. He will replace the memory but you guys who are overclocking or have your memory in manual take heed. Canopus doesn't have a clue why this effects their cards.
