QuickTime Bugs?

Since upgrading to FCP HD and all the new versions of LiveType, QuickTime, Compressor, etc, I have noticed a major problem with LiveType fonts in my Final Cut Pro projects: they are all dirty and pixelated and chunky. What the...?! When bringing the text into FCP it looks just fine and dandy:

But after you render the text it looks like this:
text_bad.jpg

Viewing the video via FireWire to an NTSC monitor shows nice, crisp text BUT the BIG problem here is when you make a QuickTime movie for the web the text looks all chunky and pixelated and gross! I cannot get around it. Anybody know the answer?
