I've recently reinstalled my gbpvr and removed all data in all catalogues. In the process the old recordings (which still exists) is gone, is there any way to enter them into GB-pvr?
Each night with the EPG update GB-PVR creates recordings-dump.xml list of the recordings in database. If your problem has just occurred, then this file should still contain your list of recordings, and can be imported with the 'import recordings' feature in the config app.
