Richard,
YES, this is the best way that Zolotroph explained. I owe you one from that audio thread, thanks so much ’cause it’s all working great.
You can do all your projects for DVD in the DV setting, and when done convert the sequence to an uncompressed codec. Render, make a movie to put in Compressor and make your DVD, your graphics will look fantastic.
Zolotroph, glad to hear from someone else who’s taking advantage of this really cool workflow.
