I'm trying to run my PS2 on my computer screen since i don't have a tv. my tuner card has a composite video in, but i can't figure out how to make it all work in GB-PVR. could somebody please help me.
my guess would be chaning the setting for your recording source. See what other tuning options you have, by default it is on antenna, witch would be the coax input on the card if I guessed right.
You'd need to create capture source, configured to use the 'composite in'. Set the EPG Source to 'none', and manually add a channel called something like 'PS2' or 'Composite'. Now when you view live tv you can switch to this channel.
That said, I think the delay added by the PVR card will drive you nuts try to play games.
