I am saving up my pennies to buy an Apple TV. 160GB is still tiny for the amount of TV Shows and Films I have (I have 2 other flat mates and together we have a ridiculous amount of DVD's). My MacBook Pro hard drive is pretty full from 60GB's worth of music and over 3GB's worth of photos, as well as all the other crap I have on it. This leads me to ask this question - what is the performance like if I had all my movies and TV shows on my external hard drive plugged into my Airport Extreme? I've had a similar setup using Front Row and AirDisk (just made a shortcut to my external drive in my Movies folder) and occasionally the media would stutter. Note I haven't tried this since 10.5.0 because the performance was crap. Would using Apple TV provide better performance in terms of buffering to prevent things like that? Also, would streaming HD video in .mp4 format work smoothly over AirDisk? Anyone got that as a setup?
