I have a strange new observation to share: I have a 1tb internal HDD and a lot of it is full with PS2 ISOs and installed game data and PSN games. Last time I checked I had <60Gb of free space. As I was fiddeling with some of the installed software (Star Ocean 2 (PS2), Beyond Two Souls (PS3) and Netflix) I noticed some video stuttering and audio drops. At first I thought it was some homebrew that got in the way and tried wMM, sMan and Managunz to boot the games but it made no difference. Now I took some of the installed PSN games and converted them to ISOs to free some internal space. (Yay to PSNLiberator!! ) I have now around 70Gb of free space and the stuttering is gone! Has anyone else noticed someting like this?
