I am very illiterate when it comes to computer programs so I'm not sure what I am doing wrong. I have a Dell laptop and I use Windows Vista Home Premium. I plugged everything in and it seemed to work fine. As soon as I start to play the VHS it is very choppy and distorted on my laptop but plays fine on my TV. It also makes everything run very slowly. For example when I try to minimize, exit, check or un-check boxes it freezes for several seconds before doing anything. How can I fix this?
