Sound/Video Problem after Install...HELP!

[55318008]

Ok so I installed iPC 10.5.6 just fine. Selected Voodoo Kernel, ALC888 Audio, Natit for my video card since NVInject and NVdarwin were causing the first boot to hang. So it works fine, just for 2 minor problems. I have no sound, and the video seems like it is 'tearing'.

Picture of the tearing...

I apologize for the quality.

Any suggestions as to how I can fix this?
