CDBURNERXP (works fine on 7 here)
IMGBURN (for times I want it's features)
DVD FLICK (man that's good stuff)
Hope this helps. All are free.

My old HP computer (with Windows XP) came with Sonic Digitalmedia Home software on it; a great, easy to use program for copying and burning CDs and DVDs. My new HP (with Windows 7) did not come with Sonic on it and I can't seem to find it to download anywhere. Any ideas?
