Here's a newbie question. What is the best way to upscale a digital picture, grabbed from a digital betacam (TGA, 720x486, 72dpi), to a print quality image that we can use to create the DVD cover ?

Pierre,
Check out Genuine Fractals. Good algorithms for enlarging without artifacts and noise. If not try going artsy with the capture to B/W or duotone with effects or high contrast. Use the noise from the enlargement to your advantage.

Sadly with an image at 720x486, 72dpi you are unlikely to get a good repro over an image size of 6.5cm x 4.1cm (300dpi). Whilst Genuine Fractals is a good program, it is aimed at really big enlargements, anything up to roughly a 300% enlargement is better done in Photoshop on a bicubic resample under: Image>Image Size.
You will be able to push the size up of your shot a little, but you'll soon see the limits of your image.
