Replay Video capture PROBLEMS

Okay, I have RVC on a very high end machine running:

2 Gigs of Ram
2.66 Ggz Processor

Problems: I am trying to capture iTunes Videos I have set to RVC settings to wmv using RVC and,
it JUST DOESN'T WORK...:mad: It states 0.01 MB and, stays that way. No matter what windows size I use in iTunes. :( Nothing works! Here is the big problem: when you click on stop it never stops and, I can not shut down the program either....and, I can't even close it with Task Manager either....:confused:

Version: 3.0. 10.07.08

So, I'm stumped. And, how about offer a .avi format support (XviD/DiVX)?
