While connecting my second HR20 today in a room that only has 1 sat feed and 1 OTA feed I discovered that the HR20 will do something that my old HR10 Tivos would not do. It will record two shows at once even when you only have 1 sat connection. I tried the following and was successful: 1) Record 2 OTA shows at once 2) Record 1 OTA show and 1 Sat show at once 3) Watch an OTA channel while recording a SAT channel 4) Watch a Sat channel while recoring an OTA channel When I tried to set up 2 Sat recordings, it tells me that both tuners are in use but shows only the 1 current sat recording, and asks if I want to cancel that program (Exiting backs out with out canceling the current program). This is AWESOME - most of my recording conflicts are usually broadcast network shows, so the fact that I don't have 2 sat feeds in the room with the new HR20 is now no big deal. Sorry if this is very well known. I'm just excited. EDIT - after playing with this a little while I've determined that I must employ some of my own logic to the prioritizer list for everything to work perfectly. I prefer to record off of MPEG4 because they are more reliable than the OTA locals, however OTA are fine if that's the only way I can get 2 shows recorded at once. Will have to babysit the ToDo list for a while to see what massaging needs to be done to get maximum efficience out of this type of setup.
