Sorry - I know this is off topic so I'll keep it brief - it may affect some others here. My Sky+ box has no problems with Channel 4 +1 but while testing the new channel logos earlier on I discovered that my second Sky box, connected to the same dish and in the same rack of equipment almost completely fails to display the +1 channel unless I turn off the DECT phone base station (or make a phone call on said DECT phone!) Apparently this is a known problem. The down-shift frequency used when converting the signal from the dish's LNB to the set top box for the transponder used by Channel 4 for their +1 service is roughly the same as that used by DECT base stations. I have a known shielding issue with the main input component on my aging Sky box and I guess this is the first time it's manifested itself as this is the first time I've tried picking something up on this transponder... I hope this helps/explains if someone's scratching their head wondering why Four+1 (and the Big Brother live stream) don't work but everything else does.
