W880i video playback

Hi everybody,

Yesterday I flashed my w880i phone (for unbranding purposes). I got flash menus, a "My Shortcuts" function and more. But when I play a video in full-screen mode it looks very pixelated (before flashing it was pixelated too, but the effect wasn't so strong), maybe because the phone lacks on a interpolation algorithm. Is there any way to get more-smooth video playing back?:confused:

Open video from Menu > Entertainment > Video player

play any video and click More > View mode > Landscape
More > Video size > Original
