Homebrew 240p looks off in Not64

[shatterhand]

I tested out 240p in Not64 but it doesn't look right on my standard def Trinitron CRT. I can see the blank scanlines you get with 240p but the picture looks jittery when I play a game in 240p and I don't have this issue when I run other homebrew in 240p on the Wii. Does anyone have any idea why this might be?
