ATV1 With Broadcom Crystal HD Video Card
Log: http://pastebin.com/5B60gFPB
Media Info:
The video plays fine on a Mac using the same XBMC version and on an ATV2 using the Eden Beta from the same date.
The video library is on an external disk of a MacMini. All instances of XBMC use a shared MySQL Library.
The ATV1 is hard wired to an Airport Express. The Wireless AP is an Airport Extreme. Here's a graphic showing signal strengths, noise levels and transmission rates:
As you can see, the ATV2 has a much slower wireless transmission rate, but it plays the video flawlessly.
The video is choppy and stutters even if I copy it to the internal drive of the ATV1.
Why does the ATV1 constantly buffer this video?
