Advertisements We just had a Sky engineer in to fix a problem with some channels missing. He replaced the box, so we now have an Amstrad Sky+ box instead of a Thompson. After he'd left we found that the Tivo could't change TV channels reliably until we changed the IR settings from fast to medium. Then we noticed that we couldn't select radio channels at all. We can select radio channels directly on the Sky+ box, but when the Tivo changes to a radio channel we never see the leading 0 being sent. e.g. change to radio 4 0104 always ends up on Channel 4 104. Any ideas what we can do? My guess would be that the Amstrad is taking too long to respond to the Sky key and missing the first 0 in the channel, but that's only a guess.
