This is what he says, "I have got custom firmware 4.01 m33 on my fat psp, and when I am watching movies, the volume automatically mutes. The iso (game) I used to play before does not work anymore. It tells me 'the game could not be started'. What do I do? Sometimes it (the game) hangs and I usually have to pull out the battery."

To answer your second question, you should go to xmb (psp's main menu) and press select to access the vsh menu, then change the umd mode to m33 driver.
