no problem, im using 5.5.10.42 and have had no problems with it. I've only done dvd videos with it though.
I reckon you should move on to Record Now Deluxe, it is far better for DVD Back Up: http://www.chrismccann.co.uk/recordnowmax.htm
Nero is free, you just have to go throught the pain of downloading a new version ever month. Or just buy it and no more wories. Oriphus, why do you keep pushing Record Now Deluxe? Do you find it beter, or are you geting a comission. Personally I have always liked Roxio6. Its not free, but I have used it the most and has lots of associated features.
I dont get commision on it, though they did send me a free copy of it in return for their user guide. The reason i push it quite a lot is because it is the only burning software that i have used that i can truely found to be perfect for copying DVD's. Nero is not free, you can only get free updates for the sepcific model you are using IE: 5. Roxio, i am not as keen on.
