an..odd screen glitch

It's just been one problem after the other today with HBC, but I finally have it all sorted out...save one thing

I'm getting a very odd problem where whenever I boot a Home Brew Game/app, the top and bottom go off the screen, making many games unplayable.

Any ideas?

using an LU 34 wii, latest homebrew channel and wii menu version, Traveler 4 gig SDHC card.

What games you talking about? not enough info.
n64 by any chance?

I'm talking about all sorts of games. Still alive Wii, Super Mario Wars, Sega genesis emulator, and even harmony at one point, although for some reason that fixed itself.
