See if you can track down Philexile on here or other xbox related forums. He's a nut for scanlines and can probably guide you to exactly what you need.

This can maybe be inserted into dvdplayer, by someone, as a filter, for video playback, but I'm not a xbmc builder or insert a scan line into your skins video full screen for a quick way to get scanlines
Have you tried different video leads?. Have you tried routing your power lead away from the video leads?. Have you tried the Xbox on another T.V.?.
Have you tried a different power supply in your Xbox. Have you tried the different settings in the video interlace on XBMC?.
If you see the picture in my original post, that is from an emulator, which has a software filter to acheive the scanlines. I was hoping this could also be done for XBMC.
hey guys its been a while since I posted something glad to be back was away, anyways go this little trick I found online its not mine but it be great to try out for xbmc4xbox to add scanlines to video playback
