On my old system I had one H2/Sling; one super Joey; and one Joey1. My new system has one H3/Sling; and two Joey2's. I tried a few more things:
1. Used PAUSE to stop the program ; then went to a different live program; and as long as I chose the PLAY button, I was able to "resume" where I left off. Again, if I SELECTED the program, I didn't have any options except for LIVE or START.
2. While doing all this I also went to one of the Joeys... and as long as I found the program and hit the PLAY button, it gave me the option of resuming where I left off on the Hopper. After doing all of this and going back to the HOPPER, I found the program and hit the PLAY button, if very nicely gave me all the choices I needed (ie, it showed where I had paused on both the Hopper and Joey, and I could chose either of them or go back to the start,,,,,, in other words everything to me worked as it should!!)
3. So the bottom line to me is that as as long as you hit the PLAY button, you are able to PAUSE/RESUME a program that is being recorded just like one that has finished recording. The only slight mystery to me is that when I go back to a program where I have paused or switched-off by going to another program... it appears that it is a few seconds past the point where I actually left it!!
