it seems that when i record off my tv card (CVBS) playing ps2 there's audio delay after 5 minutes or so. it's always after the 5-6 minute mark. it's fine before that. it's not a bad delay just like half a second or a tiny more. has this got anything to do with my cpu stats as i'm on 512 ram and 1.24 ghz cause tv card winfast application is high on that. any ideas?
