Hi
I’m using cs4 on a pc. file – export – media allows you to export in a format of your choice. under export settings you can choose differen formats, output name allows you to specify file name, location, and depending on format you choose there are a number of tabs underneath which allow you to change video, audio etc settings. Media encoder allows you to queue files up and render them in batches (good for leaving on overnight)
microsoft avi has pal dv preset, but I’m no expert on the best formats to use for dvd.
If you get any decent results let me know your settings because I’m struggling with image quality myself at the minute!
