Ah, okay - so you've already exported it from MixEmergency. Well, the video will need to be re-compressed into a format compatible with DVD players, but not by MixEmergency, by whatever DVD burning software you use. I'm not sure if you've created a DVD before, but most software will take care of the format conversions for you. Do you have any DVD burning software? Do you need titles, menus, etc? Most Macs come with iDVD - which is apparently quite easy to use (I've only used it twice myself). There are a few problems if you're trying to burn 16:9 movies onto it I believe, or at least there were when I last used it, so if you're having trouble doing this, then let me know and I'll see if I can find you a link. iDVD can be quite useful as it allows you to write the disk to a Disk Image (DMG) file, so you don't need to re-compress the DVD each time you wish to burn it. There is other fairly simple software, such as Burn: http://burn-osx.sourceforge.net/ which you can use (I have only tried Burn once, and that was many years ago now). Otherwise you can get more professional products such as the ones included with Final Cut Studio.
