Sony DCR-DVD 101: filename visible for playback

I've put together a video with footage taken with my Sony DCR-DVD 101 using ImageMixer.

When viewed with a variety of media players on a computer, the video plays fine, but when played on a regular DVD player connected to a television, the filename and date are imprinted on the movie throughout.

We've contacted Sony and they claim that the only way to rid the video of that is to reshoot the entire video with one of the settings on the camera changed, but I'm hoping that there's a way to remove it from the footage we already have.

Any ideas?
