Hi Glenis,
PowerDVD doesn't do this, but both PowerDirector and PowerProducer let you capture not digital content onto your computer.
To do this, you need:
1. To have a way to capture non digital content. I.e. TV Tuner card or a way to capture with your video card.
2. Program like PowerDirector or PowerProducer.
What format is the original non-digital footage in? PowerDirector and PowerProducer let you capture from a TV and/or VCR. You just need to have the right video input into your computer.
Hope this helped
Dave
