h.264 two-pass encoding had problems with degraded quality in CC (7.0 and 7.0.1). The update that went live today should fix that issue. Please update, try encoding again, and report back here whether the quality is up to snuff.
Unforunately that didn't do it. The intro I have at the beginning of the video (that I created in After Effects) is no longer pixelated, but the rest of the tutorial footage still is. I can post the original video file and the exported file if that would help. It will take time to upload to my web site (I don't want to upload to YouTube, as their back-end processing would interfere). I'll embed the files tomorrow
Ok here are the videos ... one section of the original raw footage (in AVI), and then the final, edited video (in MP4):
