Im having problems adding/viewing video clips with my Rokr. i converted some .wmv/avi/mpeg videos to the proper Mpeg-4 format the Rokr plays, but for some reason after adding the clips..and i try to view the clips, i get an error, i think the video resolution of the clips are too big...325x180...and i think the Rokr allows 176x220..does anyone know how to resize video resolution, and what programs to do it with...virtual dub does not work btw
