I'm stumped with an issue i've had while streaming video on every encode i've done so far . . . if i transfer same encode to apple tv's hard disk it works flawlessly. It seems to appear right before the chapter marker at the end of a scene. shouldn't be network speed - connected via ethernet, shouldn't be host computer - brand new quadcore computer fully loaded. All encodes were done using the standard apple tv preset in handbrake. It has to be the way the box handles streaming or I suppose it could be a vista issue, are there any known issues i'm missing?
