I'm using Movies on DVD 7, I can record video and sound OK using the USB video convertor. But the preview screen remains black before, during and after recording. The preview box is, of course, ticked on. Sound is OK during preview.

The only video driver I can select is 'USB Videowandler 2 (USB - Dshow)*.

How can I get the video preview to work? It can't be a hardware problem because the video does record.
