No, I can't capture unfortunately. I would love to be able to, but surround sound is first on the list when I find a spare £150...
Plus, I've got to play Mirgervin so it's probably moot anyway
EDIT: Although I gather anyone with a DVD recorder can capture, but it's a bit of a long winded process... play the PS3 through the recorder and record the output to DVD. Then rip the ISO on PC and convert to AVI or something...? It's all theory that I read somewhere so couldn't tell you if it would work. Sounds feasible to me though.
