The IceGuide was correct and had been amended with plenty of time. I suggest checking your 'fetch' times.
With respect, some of us are on IceTV clients (such as EyeTV) which can only download guide data once a day and don't give users a choice as to what time of day the download happens at. Mine seems to be at 3 am, for better or (in this case) worse. For an EyeTV user, "plenty of time" is at least 24 hours.
I interpret the fact that there's an IceTV logo on my EyeTV EPG screen that you folks at IceTV are happy with EyeTV's use of the IceTV service, and endorse its once-a-day downloads of guide data as within-spec. If that isn't the case, it would be nice to have something that I can take to Elgato as evidence that they have work to do with their IceTV implementation.
(To get back on topic, yes, I have missed this episode too.)
