Here's the story. I'm ripping my CD collection to Apple Lossless files (and LAME-encoded MP3s) and adding in the artwork. After this much work, I want to back up the files to DVDs so that I don't have to do it again if a hard drive goes south. I'm creating MD5 checksums as I go, but I'd like to be able to verify the on-disk contents as well, without copying them all off the DVD to create the checksums. I have to do that now, because the apps I've tried (like checksum+) try to write the resulting MD5 text file into that directory, which obviously it can't do to a read-only disc. Any thoughts on an elegant way to make sure that burned discs are verified as accurate, after the fact?
