Rec'd my new 802.11n AEBS yesterday and connected an external drive to it as a movie server. I have both MPEG4 (from Handbrake) and ripped DVDs on this drive. In my home theater I have a Mac Mini Core Solo and use Front Row with DVD Assist for playing ripped DVDs. The Mini is connected through its 802.11g Airport card. The MPEG4 files play just fine, without any dropped frames. However, starting the movie and using the ff or rew buttons results in a stall of several seconds - presumably from Front Row re-caching the data? It's annoying, but othwise the movies play fine (DVD size at 1000 bitrate). However, playing ripped DVDs is unacceptable using either Front Row or DVD player - lots of dropped frames. On my other Mini, a Core Duo connected to the AEBS by ethernet cable, it plays the DVD files just fine. If this drive is connected to the Mini by firewire, it plays DVDs just fine. I suspect the Solo is having issues with the wireless transmission, thus I'll likely be running an ethernet cable to my basement. It's too bad they do not have the n card - maybe in the next Mini update (along with C2D).
