Thanks man! I fixed the screen tearing and quality issues by simply upgrading the Windows Media Player codec so that is now solved.

So DVD format is really only a MPEG derivative with chapter points and the like?

Also, when I export from PremierPro1.5 all I am doing with the video after that is setting it up in NeroVision for the final DVD, with no further actual video editing. So knowing this, do you recommend I still use AVI in the stead of MPEG? Is the quality of MPEG the same as DV AVI?

I am editing video for a group of doctors teaching a procedure on dermal fillers and all of my scenes are zoomed up shots of the lips with insertion and extraction of the needle so I need maximum quality. I think NeroVision will do exactly what I need to do and aside from that I have about 3 days until my deadline and I havent begun authoring the DVD so I have about 72 hours to get this done. Thanks again man.
