Dvd recorder DMR-EZ25EB record/watch?

I know this must sound mad, but can I watch another Freeview Channel while I am Recording another Programme on Freeview? I am a complete dummy when it comes to reading Instruction Manuals. I have Freeview on AV1.One other thing, on this recorder I have been getting messages suggesting a DVB Auto Change Set-up,which I have been refusing,is that wise? Help appreciated.
