When TiVo encounters a recording clash, it will (by default) clip the lowest priority recording by up to 5 minutes, instead of cancelling that recording.
That sounds nice, but, why have your recordings clipped? Why not have the whole recording plus your padding too? There is indeed a way to have all of your cake and eat it too. How? Simple:
Turn off Overlap Protection.
What I hear you cry?
Didn't your father teach you to always use protection?!!? Bear with me.
TiVo is smart, in that when a clash occurs, it will attempt to locate a repeat of the cancelled recording and it will record that instead. For Series Link recordings, it will search for a repeat on the same channel. For Wishlists, TiVo will search all channels.
Turning off Overlap Protection tells TiVo
not to clip any recording when there's a clash and to
always hunt for a repeat to record. The trick is, to
reorder your recording priorities so that the programmes which aren't repeated have higher priority compared to the shows which are repeated. As I've previously stated, you can have a quick look at the upcoming episodes list to see if episodes of a programme are repeated throughout the week.
For instance, I've noticed that programmes broadcasted on BBC 1 HD (including the likes of
Doctor Who, Merlin and
Waterloo Road) don't seem to be repeated on that channel, but they are repeated on the BBC HD channel (
while we still have it that is). If you have a Series Link for a BBC 1 HD programme, give that high priority.
If in doubt, give your Series Links higher priority compared to Wishlists. A Series Link for
Castle on Alibi for instance, will hunt for repeats on Alibi, whereas a Wishlist for the same programme will find repeats on Alibi, Alibi +1, Alibi HD (when that launches next year) and any other channel
Castle is on.
Overlap Protection is switched on by default. Since turning it off 3 weeks ago, I've not missed any recordings, and that's with padding set to 1 minute before and 5 minutes after for all recordings. There's some vigilance required on your part as far as checking for repeats is concerned, but in return you can use padding without worrying about programmes not being recorded as a result of a clash.
Still not convinced? Well, bear in mind that when Overlap Protection is on, and a recording will be clipped by more then 5 minutes, TiVo will cancel the recording and go hunting for repeats anyway.
