[MENTION=13]Redemp[/MENTION] (FYI) I noticed your Quake Main Menu Skin is causing some issues. Results in a Blackscreen freeze. I had a few like this in the past and i could never figure it out.
Was making a Quake package yesterday and i couldnt figure out why it was not working, but i tracked it down to the main-menu skin. Changed that out and all was okay.
Here is one that is similar to yours.
(I need Clean up the image a bit (a few rough edges), but was to test)
Edit: Could just my PS3 also, it has been acting weird the past day or show, i think my internal HDD is going bad.
