AVCHD to DVD: Export Options?
I'm currently editing a school show in FCE, shot on a multi-cam, AVCHD camcorder set-up. I'm editing the files in native format because a few copies on Blu-Ray will be needed. My problem is this; what export settings do I need to apply to the finished edit to optimise it for DVD burning, as 95% of required copies are on this format? I've tried the standard Export/Quicktime Movie option, and whereas I can burn lovely, pristine Blu-Ray copies from this file, (using Toast 10 Titanium), when I try to burn the file as a DVD, (using Toast's DVD burn option), the disc when viewed is of a pretty low quality and horribly interlaced on anything that moves even slightly. I'v tried customising the settings in Toast, specifically selecting "progressive" in the "Field Dominance" option, but the burn still looks crap!
I'm wondering whether my problem starts within Final Cut Express somewhere. If so, what is the optimum export setting with a view to creating decent-looking DVDs?
Thanks
