For some reason when I edit anything and render it to an MPEG-2 in Vegas, it takes a long time for vegas to render and the quality is unuseable. But if I render to AVI and then let DVD architect render to mpeg-2 (VOB), the quality is fine even when the file size is smaller. How do I get Vegas to render video files that are as good as the one DVD architect renders.

Is it possible that a registry value is incorrect and that Vegas is actually making a huge MPEG-1?

One example is: I can use DVDshrink to grab a single scene from a DVD. I can add the resulting VOB file to Vegas. Add a wav file and perhaps other audio. I then render it to an MPEG-2 that is considerably larger than the VOB file but full of digital artifacts, striated smears, etc and it takes about 10 minutes per linear minute to render with NO EFFECTS just a straight audio overdub. But if I render it to an AVI, it takes just as long to render, creates an insanely huge file (About 1G per minute) and then that file if put into DVD architect comes out as a small VOB file and the qaulity is perfect.

I am trying to edit instructional videos that use clips from popular movies as illustrations (copyright covered by CVLI license). It takes me so many extra hours of rendering to bypass the unuseable quality of a Vegas render.

What gives? Is there a setting I have overlooked or a dll I must replace?

Thanks.
