Normally it does have logic for the unique_id with North American data but because you used my FTR import utility your database is rather unique could you upload your logs?
Sure. The thing that was throwing me off was that I went through the list of Pending Recordings in NPVR and cancelled the recordings for two days that were duplicates and yet when the EPG is updated they are re-scheduled.
I did notice that you have changed some of the rules that the import made for you. NextPVR won't be able to prevent duplicates for those files anymore.
I had the same problem with it. There were like 5 or 6 series that had problems, but it was easier to just re-add them. That's part of the reason I want to be able to review the guide and mark some things as already watched. I had to do that with FTR and as long as there are only a few shows it only takes a couple of minutes per night. I thought that cancelling the recording would do it, but that doesn't appear to work.
