Currently using MBP 2.53 Ghz with 4GB RAM. I've always been using PS3 Media to stream my mkv and other HD films/movies to my PS3 and never had any problems. The last two nights, I've recently been having a weird problem with playing/streaming movies: it stutters and mocks about after watching 1 hour and 20 minutes ++! The last three films I watched all started making funny stutters and out-of-sync voices after 1:20:00. I never used to have this problem and I don't remember changing anything drastically with settings etc. I am currently streaming via gigabit ethernet cables through an Apple Time Capsule. I first thought that the movie file was corrupted but when watched locally on the Mac, runs without a hitch! Is it a memory leak on my Mac? Is the PS3 Media Server having buffering problems? Is there any way to reset the PS3 Media settings?
