Just thought I would chime in and advise that I'm using the icetv EPG on my Win7 HTPC and it installed without a hitch, updated and downloaded with no problems, and subsequently set the channel listings to the correct -icetv properly without any input by myself.
So far working perfectly.
However seeing as the sole reason I have signed up for icetv is the ability to set my htpc to record shows remotely via the web interface and mobile site, I am keenly waiting for this functionality (along with everyone else I assume!).
Fingers crossed we're not waiting *too* long.
