I just updated rockbox on my player and i am now having an issue with video playback, the screen shuts off after a second, if i press a button it comes back on... for a second.
another thing, i'm not sure if its material, but i have a couple videos on my microSD card and when i select those, it give me an error message reading "missing packet start code prefix: FFFF at F000", but since i don't get that error with my other videos and they all still have the above problem of screen shut-off, i'm not sure if that means anything.
