OK, I'll reply to myself. Here is what I have found. I took another system and reloaded it from scratch. Win XP Pro (NO UPDATES AS OF YET) So I have a fresh load of windows and Microstudio V2.400. Everything works just like it is supposed to. So now I will start with Microsoft updates one by one and see if one of those was the problem. I can now read a full Karaoke CD in about 8 mins.
