I've found a problem with the AltEPG image when using 'Record by channel'.
When I get to the screen with the date / channel / programme listing - if I select the channel with the up/down buttons, then no problem. If, however, I enter the channel numbers directly, e.g. 103 to jump to ITV1, then the EPG shown is for the alphabetically first ITV1 region, which is Anglia. Same happens with BBC1. I'm on Virgin Cable.
However, because I'm in a different region, and my "Channels I Receive" are set up correctly, I can't pick any programmes on ITV1ANG or BBC1XYZ. I have to go "down" a channel, which then brings up the right EPG region.
I'm guessing it's an error in the AltEPG ISO image, because I've not seen this problem before.
