We, like others, have struggled with one particular problem with this card in that when connecting a VHS deck to the card via composite connections, the video would frequently "black-out". You would lose audio and video for a second, it would then return for a couple of seconds, but would then "black-out" again. Other video sources using the same composite connection all worked fine. It seems that there may be a problem with the signal strength or format coming from the VHS deck. Blackmagic support suggested that perhaps the VHS deck in use was not supported, but others have reported this problem with an array of VHS brands and models.
We solved this problem using a simple solution -- convert the composite video signal to S-Video. Using $40 in parts from a local computer store, we attached an RCA-to-S-Video connector to the back of the VCR, and then attached, an S-Video to dual RCA cable, which then plugs into the card itself.
