Last night, my wife asked me to record something she'd spotted had just started, while I had the guide open. The box was already recording two shows, so it asked me which I'd like to stop to allow this new recording. I canceled this and thought I'd just use the web-if to find a repeat showing. I then absent-mindedly just pressed OK on the remote, and the box happily tuned to the channel and we started watching it. Whatever I did, the thing wouldn't let me record what was being watched. I understand that you should be able to record more than one show from the same multiplex at the same time, and I'm sure I've had three simultaneous recordings happening before. I'm fairly sure two existing recordings were Dragon's Den (BBC2) Doc Martin (ITV1) and the new one was Hotel Inspector (C5). The first two are on MUX1 and the last MUX2. Whatever the muxes, why couldn't I just press 'record' when watching?
