I have a number of series link + programmes set to record on new only. However I have noticed over the last few weeks that programmes will record again. The only difference is that on the second recordings the Series and episode details are missing. Otherwise the programmes are exactly the same. A bit irritating really.
By means of background explanation, the reason for this is (nearly) always because of the EPG (TV guide) data, on which your TiVo/V6 relies when setting recordings - to be precise, the "first aired date".
As @ozsat has mentioned, if you can post specific examples on here, then they can be checked. There's also the tivoguideerrors email inbox that errors can be emailed to for fixing - but it's always worthwhile checking with the broadcaster's website first, as some of them are more prone to errors with their own schedule, than others.
