I have noticed this problem for a few weeks now.
We have a series-link set to record "Come Dine With Me" choosing first run and repeats.
The show runs weekday afternoons but TiVo refuses to record the Friday episodes, even when I select the Friday episode on it's own and ask it to record it specifically.
I notice that when I select the Friday episode in the guide and click the record button I don't get the "Record as planned" option that I would expect with a show on series link, just the "Record This Showing" option, which I select. But it still doesn't record it.
Annoying especially as Friday is the finale of each 5 day competion.
I have not other conflicting recordings set to record at the same time. I sat here today and watched to see if it would record but no joy.
Anyone else noticed and possibly rectified this problem?
