I suspect that Zap 2 It has their xml feed all screwed up. IMO, Zap 2 It has been the weak link in the media center for a long time, providing all sort of wrong broadcast data. So not a surprise here.
Is everyone here on Vista MC? Not TV Pack or Windows 7? One theory is that Zap 2 It has fixed stuff for the new sub-channel structure in TV Pack and W7, but in the process broke VMC. But this is total speculation.
I recommend waiting til after June 12 and doing a full Set Up TV process. This is something I was going to have to do anyway because CBS is Chicago is switching broadcast frequencies.
