I've been searching around but can't seem to find a thread on this... I just got a second TivoHD for the bedroom. So I now have one in the main room and one in the bedroom.
I activated the new one on the multi-DVR discount and I made sure both were set to transfer and allow video downloads in the preferences.
I set it up last night and gave it overnight to update/etc and for the account to update. The new Tivo is getting TV just fine.
BUT... The new Tivo appears as "DVR" at the bottom of the "Now playing" list on the original Tivo. That looks great. But the reverse is NOT happening. The new Tivo does NOT see the older one...
Am I just not waiting long enough for it to appear?
