And regarding the jerky video it could be two things:

1. I only rendered that clip in WMV so it's not 100% quality and it's also only in 2.1 audio.

2. Perhaps it's your video card?

I did notice the shaky video on YouTube but the WMV isn't too noticeable. Again, I didn't render that clip in 100%. In Vegas it looks fine so no worries. ;)

It has nothing to do with the video card, but the framerate of the clip. I could happen if you're working in 23.976 fps and exported to 29.97 fps for example. Or if your source is not IVTC'ed and you're editing in 29.97. You SHOULD be working in 23.976 fps.
