When trying to use "Burn Disc" in DVDit Pro HD, after I "Simulate", with no errors, and after I click "BUrn Disc", it starts to render menus and stuff but then gives this error:

operating system error: number = 0x00000020 - The process cannot access the file becasue it is being used by another process.

I have tried quiting evey other program and restarted with only DVDit running but nothing works. Anyone knows what this means. Anyone knows what I can do?

Thanks.

Have You tried muxx all your images to another drive?

Try "Burning to Volume" and see if you can do that... If you can then you can use Nero or something like it to burn to disc
