Ah, I understand what you are saying now. Sorry. You can't add a second simultaneous recording. If you are recording the channel you are watching but then change to another channel, your initial recording will cease. You therefore cannot accidentally record a second channel.
With regards to you receiving a warning message if you change over from the channel you are recording, we are sadly not as advanced as that yet... but it is a good idea. Perhaps in time, someone will create the necessary firmware to allow this to happen but at the moment, IPTV is still relatively primative. Personally, I am just grateful that I am able to record one channel (admittedly, this is restricted to the channel you are watching) thanks to the H.2S. I know that alot of boxes on the market cannot even do that.
