When I 'scratch' or export my video, either the title (plus the audio) or the video (plus the audio) display, but not both. Which displays depends on what track I put them on.

The title file has a blank background set, so I don't think that's the problem.

It's weird, as I used Premiere before years ago with no problems, but not on this computer:

Compaq Evo N400c laptop
850 mhz
256 MB RAM
20GB HD.

Files are on external 300GB HD with a firewire connection.
Main AV file is an mpeg 2.
