lol i guess you're right.
But what i'm looking for is something that would just fill the disc with ecc info... If the data on the disc was that important, then i would make a backup disc. But when you burn a CD and leave say, 100MB unused on the disc, it would be nice to put that 100MB to use with error correction codes.
If it doesn't exist, it wouldn't be too hard to code if someone knows a good error correction algorithm
