I've read mention that having multiple recording formats can cause problems with extraction and that if all recordings were of the same quality setting that it would most likely eliminate these problems. So if I wanted to start over fresh and have my backup from mfstools to restore, how do I reformat(or do I need to) the Tivo for the filesystem it has ? Or will the mfstools restore option essentially reformat the disks ? I'm not trying to save any recorded programs so they can all be blown away.
