I have seen on the forum that some users have been able to stream multi room on Wireless N. It also appears Tivo may have originally supported it and then changed. My question is for those who have done it sucessfully, has Tivo made a change to hardware or software which no longer allows it or just won't support it. Due to my expected location of the one unit which will be on N when all set up, I think I could be sucessful if still allowed. For reference, the other is further away from router and has ethernet. Other question is for FIOS users. Does Verizon always install MoCa regardless of the equipment requested and will the testing they do reliabilly inform me that MoCa will work well? Can I expect adding the Tivo bridge on the Premier and using the built in bridge on the XL4 to be reliable or is it worth spending a day in the attic running Ethernet?
