ok I finally figured the whole airplay ,atv , bad sync and lag problem I was having. Turns out, my lynksys roughter was not able to handle ipad2 ,fast enough. I went to apple store with my ipad2 and we connected to their wireless Roughter named Apple AirPort Extreme and their apple tv device. I then attemped to play rr2hd and was very please to see no lag !!!! and also other things like music played great with no drop outs. I quickly bought the Airport extreme roughter. This new apple roughter has been designed for the iphone , atv and the ipad2. it has to frequencies 2gig and 5 gig out put networks combined .Tom very happy now ha
