i have been affected by the black and white video problems playing on the hdd. the videos on the ps3 hdd turn out in black but there is a solution.
all you have to so is change the frame rate of the video to 25 fps.
download this software: AVI frame rate changer if you cant find it type on google: change fram rate then click on the first one.
once you have got the software run it and browse for your file. then change the frame rate to 25fps.
if you dont know if it has been changed then you can check by right clicking the file then properties then summary then it will tell you the frame rate.
then transfer it to the ps3 then you can watch that video in COLOUR.
Mail me if you need any help with this. this is only temporary solution until sony fixes this problem
