That's a great procedure mate thanks for sharing.

I'll also point out to people that if your TiVo has a MAK and you haven't made a backup of the software with WInMFS then DO IT NOW.

MAK enabled TiVo's are unique and getting hard to find. The MAK key is not transferrable nor can it be re-entered onto any generic TiVo software image. This means if your hard disk fails and you DO NOT have a backup of YOUR software then you've lost the MAK forever.

So make those backups!
