It wouldn't have to work the same way a normal "undelete" works, where it
tries to recover the sectors if they haven't been overwritten already. What
it could do instead is when a show is "deleted", what really happens is the
show is demoted to a status not unlike a suggestion, where it is eligible for
"real" deletion should the need arise, but is still fully intact as a file up
until that occurs.
Some rules would have to be made governing whether and when a suggestion could
cause a "deleted" file to be deleted for real, but that's not an impossible
task. One potential rule: a "deleted" show has priority over a suggestion for
two days after deletion, after which suggestions will have higher priority.
That would mean if Tivo needed space, it would first look for deleted files
greater than two days old to overwrite. If that failed, it would look for
suggestions to overwrite. If that failed, it would look for newly deleted
shows, and finally if it still needed space, then a requested recording would
be bumped.
