Going to pick up another ATV2 today for a second TV in the house. This one will be located very close to my router - I've always assumed that hardwiring the ATV2 via ethernet to the router would yield better performance than wireless (G), however sometime ago on here I read a thread that suggested that the ATV2 was faster over the wireless? Color me confused. Secondly, if I rent a movie or TV show through iTunes on one of my ATV2s, will it be available for viewing on the second ATV2? Or must I use iTunes on my computer and homesharing to view on both? I've only purchased shows through iTunes on the computer; never rented, whereas I've rented plenty on the actual ATV2. If I rent on the computer, I guess homesharing will work from any device for the rental period. Comments welcome re: whether it will work directly via the ATV2s instead of using the computer. Thanks!
