According two the owner's manual I received with my Motorola 6416 iii DVR, it should do the following:
Watch two programs and switch between them using the SWAP key on the remote.
Record one program and view another live program.
Record two programs from two different channels at the same time.
Watch a recorded program while recording up to two other programs at the same time.
I am able to do numbers 1 and 2 above, but anytime I try to do number 3, I get a warning message stating that I am already recording a different channel and that it will discontinue recording the current scheduled recording.
Does anyone know why I am unable to record 2 channels at once?
I am having the EXACT same problems you are. Any solutions yet? I just got my box yesterday and am unfamiliar with it.
Also, I'm having another weird problem: when I set the dvr to record and go back to view it, the screen says "mute" and I cannot turn it off. I literally have to stop the recording, turn off the box, and then turn it back on for the "mute" to go away. Any help is appreciated.
