Can someone confirm this issue on their client(s)?
Yeah, this sounds related.I can't confirm your issue, but I've noticed a similar problem (using Maya, perhaps I should add). Sometimes it seems that when you press 'rec' on a show, in the list of airings (on the right) the first one rather than the one I chose in the EPG is highlighted. If the first airing is already scheduled for recording just pressing rec again leads to it being de-scheduled rather than the intended show being scheduled...
