TrueDisc Error Correction for Disc Burning?

An anonymous reader asks: "Macintouch has a link to a new piece of software — TrueDisc — which claims to make data burned to record-able discs more reliable. More specifically it uses interleaved redundant cells to rebuild data should part of the disc be scratched. On the developer's blog they say they plan to create an open-source implementation of the TrueDisc system, now that it is not going to be included in the Blu-ray/HD-DVD standards. Have any of you used this software before, and what alternatives are already available?"

If you are backing up important data, having the disk go bad is only one issue. I always "duplicate the data"...one disc stays home, one goes to work. No other error correction scheme will work if my house burns down.
