Hey guys.. I am unable to record videos & also cant play Mp4 videoson my N900.. my N900's camera doesnt work.. It crashes on me right when I start recording button & sometimes a black screen appear while recording.. its showing it is recording but there is a black screen on display instead of showing what i am recording..I thought it was some read only error but I have no problem taking pictures.. before it was working perfect, i could record video before but couldnt play it in it's default Media player.. but now i cant record videos & cant not play any MP4 file in Media Player.. Do anyone have this problem before, because I searched but nothing came up.. I don't want to reflash it.. Please help me..

Thank you in advance!
