Tvheadend

I would like to have an internal database where tvh stores all previous recordings.
Only sucessful recordings should be put into that database.

To become a sucessful recording there should be some options which the user can check.
- Minimum file size
- Minimum video length
- Maximum erros
- Maximum discontinues

So if a recording should be done, tvh can check if that show has been already recorded. If this check is true tvh will not record it a second time.
This duplicate check can be turned on in the recording profile.

Background:
I rename my recordings after they have been finished and move them into my global video folders.
So the recording is not longer present for tvh duplicate check.
Tvh will record the same show every time again and again. Thats not necesarry and is blocking free tuners.
Also every recording is set to failed because of file missing.

Maybe there is a way to implement such a feature.
