Build 3.1.1542
This has happened on 2 of my appletvs so far. Watching a recording and I notice a constant stutter. Looking at stats i see about 3-4 frame drops every second. If i force quit channels and reopen the problem goes away.
This just happend a minute ago. Recording was playing fine and then I skipped back a bit on the timeline. Then the picture froze. The appletv seemed to lockup and wouldnt respond to anything. Then channels crashed. I reopened channels and then i had frame drops. I submitted diagnostics right after then replayed the same recording and frame drops were gone. Also sometimes i can get it to stop if i pause for a couple seconds and then resume.
I'll try to narrow this down to a specific build...
