Output to DVD aliasing issues

Hi... newbie here...

I have 720 24p footage (HVX) that I exported from FCP as a self-contained file.

Then, I take it and compress it using Compressor -- to MPEG2 (highest quality for 120min dvd - dvcpro 720 24p).

Then, I'm just using iDVD to make a basic menu and to burn to dvd --using highest quality settings.

Before burning, when I watch the compressed video on my computer -- it looks great. However, after burning and watching the dvd I'm dissapointed (both on television and on computer monitor). I see lots of aliasing in the footage. It appears that every straight line, at an angle, is jagged looking. I don't know all the technical terms to explain what I'm seeing, but it isn't nearly as nice as I was hoping.

Any thoughts on what I could be doing wrong?

Does burning to dvd with iDVD offer an less quality than using DVD Studio?

Why do you export twice? YOu dont need to export to a self contained file before going to compressor, you can go to compressor straight from FCP. Then just make sure in compressor, that the movie is PROGRESSIVE, not interlaced, and that it is saved into the preset, just changing the settings of a preset export setting doesnt actually change it until you save it as another preset, then select that specific one to export to,.

Why would you compress it as progressive, when, on DVD, it will be interlaced?

Yes, DVD Studio Pro offers hell of better quality than iDVD.
I've seen so many people complaining about their video quality after using iDVD, and I tell them not to use iDVD ever! iDVD has a set datarate at 6Mbs whereas DVD Studio Pro offers 2-pass Variable Bit Rate, which analyze the video for the best compression.

Anyway, like Cynic821 said, you don't need to export a QuickTime file to compress it on Compressor. You can just go to "Export" to Compressor on the pull-down menu. There, choose DVD Best Quality...(whatever length you want your DVD include). It should give you a good quality DVD.
