Surprised at this one, and I hasten to add, programme scheduled for testing purposes only - honest.
Saw comments in another place (different manufacturer not Humax) re Big Brother's Bit On The Side, and difficulty setting timer for it as it is being broadcast on C5 Thur, Fri, Mon and 5* Tue, Wed, Sat, Sun.
The Series and programme crid data looked good, set it on HDR T2, and it works, so series being broadcast across channels will record if the data is correct - This is also working on the Humax SD recorder(s) as well.
