We loved our DirectTV with Tivo, but were forced to drop it because DirectTV dropped support of the box. One bothersome thing about the FIOS DVR is that it will actually record the exact same show at the exact same time on two different channels. (Less incredible is that it will record the same episode twice in the same day, but we had to let the old Tivo do that with some shows because the show's description was not enough for TIVO to distinguish episodes, and so never recorded any but the first) We are saving up our money for an XL4, but I got to wondering, would the XL4 do the same thing. We can't use our old experience because the duplicate channels are due to HD (which I don't care about) and SD being broadcast at the same time for the same show on two different channels. We did not have HD on the DirectTV. Question: is the XL4 smart enough (we are running FIOS) to not record the same show at the same time on two different tuners? Maybe it would solve if the XL4 would let me specify SD only?
