Do you have two lots of 7two channels in your PVR (and thus likely exposed to the duplicate LCN bug detailed heavily on the Beyonwiz forums)? I doubt the channel name is used, but then again you never know given there is no published information for how the ICE magic works. You said you have all EPG, does this include 7TWO? If so, then are you sure you are setting up the series recording properly? You have to make sure you don't have the series setup for 1st runs only if the show you want to record happens to be a repeat.
You might want to follow the support line thru, I think it is a form to fill out, ICE have said they don't offer individual tech support on the forum explicitly (but obviously if 5 or 6 people get on about an issue and one person found the right solution, jumping on the forum can often yield an answer, even from the ICE staff).
