I've also had problems with setting series links on my TiVo. Two links that I set to record new only have failed to identify all showings and I have had to set the missing shows manually. Just yesterday I reviewed my recordings of another series link, also set to record new only, to find that it had recorded duplicates. I thought TiVo was smart enough to realise that it has already recorded something. Seems not. The second is preferable to the first but this shouldn't happen. I hope this bug gets attention soon.
