i hit record on one channel then go to second channel and hit record. start watching first one. use the menu to play the other one. then use last to switch between the two recordings.
On my TiVo, I could pause a channel, switch to another channel, then go back to the first channel and pick up where I paused. I watched two morning shows that way. I can't figure out how to do that with my Xfinity box and a XR15 remote and I'm not happy.
adding... you can simulate that feature. press record on the first chan then same on 2nd channel. begin playing first recording then start playing 2nd recording (both in progress). then use last button to toggle between them. this will work until one/both programs end.
