all of a sudden my videos do not play. these are videos that have been on my the memorystick for awhile.when i click the video section the psp freezes then turns off. at times i can get past that but then after pressing play on a video file it freeze and shuts off.

last thing i installed was fastloader 0.7, which should have no effect on the video folder.

has this happened to anyone? ihave a psp1.50

Try moving the movies off your psp and moving them back, it might work, just a theory.

Does music play fine still?
Does fastloader still work properly?

music, games and fastloader worked fine.
i just deleted 2 corrupted videos and the other 6 video clips play fine now. i guess a few rotten apples did spoil the bunch.
