Fix videos not being marked as watched. We had some code to handle in…

…-progress recordings where we didn't have the total number of frames, this used the start/end time of the recording which can't be trusted for video because they are based on the length from downloaded metadata e.g. An episode of Frasier might only be 22 minutes long without adverts but according to the metadata it's 30 minutes. We now trust the totalFrames to be accurate for anything which isn't an in-progress recording.
