I agree. That would be great. I was able to do it with my old Pronto 2000. It was great for recording Kid's TV shows to DVD. Kid's TV shows don't have commercials in the middled so I created a macro that would get the TV show playing from the DVR, wait until the show started and then record for 24 minutes. That way I just got the TV show and I was able to put 5 shows on a 120 min. DVD instead of just 4. I was able to get fairly good battery life if I waited for the Pronto's backlight to go off first, then press the button so the macro would run without the backlight on.

I think you can do it with the Nevo by going into the setup and disabling the power off setting. I think the default is 15 minutes. But, I don't think the backlight will ever turn off while the macro is running.
