This has probably been asked before, but my search capabilities are limited at best. What is your prefered "render as" settings in Vegas? I am going to be editing some sd footage both in 4:3 and 16:9, seperate projects)

1. for DVD production
2. for website viewing (wedding video samples for instance)

For #1, I'd start with the DVD Architect presets and adjust the bitrates in those.

For #2, look at the WMV presets and pick the one that gives you the best compromise between quality and size.
