Tvheadend

If tvheadend is restarted whilst recording a scheduled programme, it is indeed clever enough to resume recording. It does this to a new file that has "-1" inserted in the filename (or "-2" etc. if it's a second etc. restart). However, the original filename is then completely ignored in the Recorder schedule, so playing back the recording will only play from the latest post-restart point onwards, which might only be a fraction of the whole programme.

Solutions to this might include some attempt to join all the parts together into a single file (risky, because the ends of each part might be truncated) or display all the parts (with some indicator to show the part number) and let the user pick which ones to play back.

It should also be noted that deleting such a restarted recording will only delete the latest recording file and leave all the previous parts on the filestore with no way from the Web UI to delete them.
