You could send us a QuickTime movie (or any other type of digital video file) to us and we could make a DVD-ROM with that content, BUT you would only be able to view the copies we make on a computer capable of playing that file. It would NOT work in your standard set top DVD player attached to a TV. A QuickTime file is not a duplication ready DVD master type. You’ll need to author the video first (adding menus, chapter breaks, etc...) so that it can be played on a standard DVD player- right now, if you burn that file to a DVD (without encoding it for DVD playback) only a computer can read it- a regular DVD player could not. You’ll need to use an authoring program (such as iDVD or Adobe Encore) in order to create Video_TS/Audio_TS folders (which are the directory structure for standard DVDs) or authored files in an ISO file (or IMG). Once you have an authored file, you can certainly mail that in to us (or upload directly through the site).
If you require authoring services, I’d recommend contacting us (or setting up a quote) that includes our authoring services.
