About every 10 mins or so, the music im playing(if custom soundtracks) skips and the screen freezes, it unfreezes in half a second. Its playable, just kinda annoying if it does it right before you need to do a reaction it throws off your timing. Anyone have any idea why it does this? My old 60gb launch PS3 did not. Moment I switched to a 120gb ps3 slim it does it. Any help would be nice.
