I am currently recording 3 programmes on 5USA, E4 and Pick, and I wanted to change the channel so that I didn't see what was happening on Chicago Fire until I get up to date.
However repeated attempts just show the message "Cannot change the channel while recording or live TV streaming"
I'm puzzled as I have never seen this message before, and I'm also a little perplexed as to how the Humax is tuned to 5USA on channel 21 when I'm pretty sure that it was on BBC2 HD on 102 when I left it.
