That is _definitely_ not a recommended use of restore. I shudder to think how frelled up your system is by now.
At some point in the near future I'd strongly recommend doing a clean install to get the system in a reasonable state, and if you have a back end problem again, post here before messing with it to get instructions on how to fix it in a cleaner way.
In the meanwhile, search for "recover" or "recovery" and "myth.rebuilddatabase.pl" which should find several threads about getting recordings to be recognized after the DB table that indexes them gets damaged. There is a bit of technique to getting the best results.
