I recently did the same, but used tar without compression. For starters most of the data I was archiving didn't compress well (like photos), but mainly if par2 fails, I can still recover at least some of the data.
With compressed files you usually need it to be perfect to recovery any data, but you can use fixtar [0] to recover some data from a corrupted tar archive.
I used BluRay as the media cost is about the same as DVDs per GB here (at least 25GB discs). Also there are HTL discs available, which supposidely have a greater longevity than DVDs.
