I am a proud owner of a brand new Apple TV and Panasonic TH-50PX80U Plasma HDTV. I am absolutely loving the new setup! One thing though... I am noticing that with everything that 'streams' from my iMac, there is a slight 'lag'. I will press fast-forward, and it will take a second or two before the Apple TV processes and streams the content change. I am considering bumping up to the new "N" Airport Express over my current "G" Airport Express, but wanted to make sure that this was, in fact, the bottleneck causing the 'lag' that I am experiencing. For those of you who have operated an Apple TV on both "G" and "N" networks, please describe for me the change in Apple TV functionality that you've noticed. Is it dramatic? Is there any remaining 'lag' with your "N" router? Thanks so much for your help!
