Hokay, got an addendum to the above.
This was the first time I tried to use it in Win7, so I thought if I just chose the right drive for it, it would happily burn to the DVD drive, not the Hitachi Life Studio drive. It won't. No matter how many times I choose the DVD drive for it, it flicks straight back to the Hitachi Life Studio drive, tells me it's not empty (too right it's not!) and won't burn anything.
If I detach the Hitachi Life Studio, presumably because it's convinced itself that's a CD drive now, it tells me to attach a CD drive and STILL won't burn anything. AARGHHH!!!!
How do I convince it firstly yes, I do have a CD drive. Secondly, it is Drive D, not Drive F. And thirdly, if Drive F, the Hitachi, is disconnected, I STILL have a CD drive, Drive D?
Worked fine in my old Windows XP, your program. I'm going to try uninstalling it/reinstalling it WITHOUT the Hitachi attached and see if that makes any difference. I think the bug, if it IS one, is that you don't seem to be able to select which drive you want to burn to and make it STAY selected while it does its thing, it seems to want to always revert back to its own choice. That's in Win7, I never had to select a drive in XP, it just did it for me and got it right.
Yours puzzledly
