Yes, that's what I get with SmartBurn too, so it doesn't appear to be system related. Guess if I want to be able to use it, I'll have to go back to the older version of Wine (though I don't remember which one that was now ).

Saving the scans with the capture button in CDSpeed 4.7.7.15 works here (see example), but it doesn't look perfect with the black borders, as I have "Allow the window manager to control the windows" checked in winecfg. Have you tried putting gdiplus.dll in the CDSpeed folder (or in \windows\system32)? This is required to save as png, I believe. I must say I use KSnapshot myself (as you'll probably know, in previous CDSpeed versions the capture button was located in the title bar and not visible at all when using desktop integration).

I'll comment on the Lite-On scans in a moment.
