Just got a roamio pro up and running last night. Downloading shows to my ipad mini worked flawlessly. But i still have a Tivo XL4 in the bedroom that i would like to occasionally download shows to my iPad... i have a tivo stream i was using before the roamio pro... if i plug that back in and put on network, will i be able to stream/download shows from my XL4 to my ipad mini? And how will that affect streaming/downloading from Roamio Pro? Does the ipad tivo app just automatically know which device (roamio built-in, tivo stream for XL4) to use for streaming/downloading from each individual box? Anybody had success with such a setup yet?
