Juan,
Give MovieCaptioner a try. It will add a text track automatically when you export as Embedded QuicktTime captions. You will need to have QuickTime 7 Pro installed prior to exporting, though. If you need to burn the captions into the video track (so there is only a video and sound track with no extra text track) just re-export again after doing the Embedded QuickTime export and QT Pro will combine the text track with the video track. You can download a demo of MovieCaptioner at
http://www.synchrimedia.com. The demo is for 14 days and is fully functional. It will do many other caption formats as well. Let me know if you have any questions about it directly at support@synchrimedia.com.
