There are other programs out there that will do split screen, etc. Actually, so many people have switched to soundcard-based operating systems, that is probably the reason you are having such trouble finding anything to use with your box. I do know that they also have firmware upgrades for older PK-232s, so you might want to find out about that, too. And see if they have the stuff still available. But you might want to contact TimeWave corp. I'm not sure if any version of PC-Pakratt will work on Vista, or not.
