I have a couple HD movies and tv shows on my mac pro. Just got an Apple TV a week or so ago. Got the whole thing setup and functioning. Apple TV says I have 4/5 bars for the wireless signal but buffers every 25-30 seconds. The router is an Airport Extreme (Time Capsule). I had it setup via WDS with another Airport Express. Neither of the two configurations work. They're just downright terrible. I've turned off WDS. I've changed the multi-cast mode from 2mbps, to 5.5 and even 11. No changes. I've changed the wireless channel Nothing seems to work. Any suggestions before I sell this piece of crap and the router, I'm half tempted to go all Office Space on them both with a baseball bat.
