My hacked ATV has been humming along find for about 9 months now. I use it to play various video files that are stored on my main Mac via a mounted Samba share. Just today, it started freezing up while playing videos. It doesn't matter what file it is...at some point, typically within 1 to 3 minutes of playing, it just stutters for a second and then completely freezes. I reboot, go back to the video I was watching, FF to where I was, and then it will happen again 1 to 3 minutes down the line. This has happened on MPG, DiVX, and XviD files that have always played 100% fine before. It seems symptomatic of either a hard drive failure in the ATV or a network problem. But since it's hardwired into a gigabit network, and none of my other equipment seems to be having network issues, I'm leaning toward hard drive failure in the ATV. I put my ear next to it while it was running (and freezing) to see if I could hear anything, but since the ATV drive is so quiet and I'd never listened to it before it was hard to tell if what I heard was normal seek operations or the clicking of a dying drive. Does anyone have any ideas on how to diagnose this? I can't live without my ATV.
