I just received ATV as a going away gift and I installed XBMC. When I bring it up, the screen is small and I can't read it from where I'm sitting. Can someone tell me how to make adjustments to fix this? My main question is: how does this software work better than regular ATV? I'm just looking for some examples because I'm new to this. I have a MacBook, iMac and PC (desktop). My ATV is syncing with my iMac, but I would still like to stream content from my MacBook. I added the MacBook yesterday, but ATV isn't showing up in iTunes today. Is this normal?
