I'm trying to export a 16:9 video clip for web using H.264 compression at 426x240 resolution from compressor using square pixel aspect ratio. No matter what bit rate I set it at -- 600kbps-6,000kbps I still get these really jagged edges. Even though my source is DV, the original file does not have anything close to this; also I have never had this issue before. One other thing to note is that if I export at full resolution H.264 -- 640x360, I don't get any stair-stepping.
Here is a frame grab of the video with the problem:

You can download a video clip of it here (data rate is around 600-700kbps):

I'm also noticing some sort of horizontal lines in the artifacts?? This is progressive scan footage shot on a DVX100B 24pA (and captured properly w/2:3:3:2 pull down removal, the original file doesn't have this)
Any assistance would be greatly appreciated. This is getting really annoying having to export huge files...
PS: I'm using Compressor v3.0.2
