Weird guide data for Disney Playhouse compared to Sky's

Yes, it's a strange request. But a sign of what some of us are facing now: young children!

Went to record a favourite movie on channel 45 (on Sky) using the Tivo guide data. The program at the time was different to the guide data. Now manually comparing Tivo guide data with Sky's, I see little correlation.

So I'm wondering where the Tivo's guide data is coming from. At first I suspected a Oz vs NZ time difference, but now I can see no obvious correlation for today's entries.

Cheers,
Andrew.
