Our Tivo box seems to have taken on its own method of recording series link shows.
I've attempted to set 2 series links tonight that are failing to record the first episode so I have had to manually record them so as not to miss the first show. Other cancelled series links are still showing in the 'planned recordings' albeit with an 'X' next to them and still insisting that they will not record due to clashes with shows that actually have been cancelled.
I have been through and cleared any old series links in case there is some sort of clash and restarted the box with no luck.
I have the same problem, I like to record the old Top of the pops programme on BBC4 but my Tivo Box will not let me have a series link, but will let me record each show manually, there seems to be a lot of glitches appearing with the Tivo system lately and a very slow response from Virgin offering any explanation on this site.
