em28xx video capture device - jitter while capturing
 

I'm getting some jitter when capturing via RCA or S-Video from an em28xx device. Help!
Input type is PAL, other than that I haven't fiddled with mplayer or vlc's options (vlc only sees the RCA input, mplayer sees both)

Have you tried switching to NTSC to see if that's the problem?
