[<Yigal>] being locked up doesn't change my situation. I am already
married.
For CloneCD: I tried and it failed.. have no idea why.. maybe its
because I didn't mark the "read sub channel" in audio and data...

Thar was on the XP - and at this time Itry to migrate all my
applications to Linux - and I wonder what Linux can offer. But ofcourse
- I need any soloution.. even if I will have to use my VIC 20
