I'm trying to get streaming VIDEO_TS working and I'm having problems. I have the latest 3.5.1 aTV installed on 2.3.1 firmware, used smart-installer, "mixed" setting. File server is a Mac Mini Core 2 Duo 2.0, streaming VIDEO_TS folders from SMB mount on the Mini to the Apple TV. This is done through a wired connection (both Apple TV and Mini are connected via ethernet to my DLINK DIR-655 (802.11n / gigabit ethernet) wireless router w/ latest firmware). The VIDEO_TS movies playback for the most part, but playback is very choppy and stutters a few times per second. Any ideas on this?
