It's Hauppauge and look at their solutions. But it sounds as if the original content is Standard Definition (SD) and you must be ready for poor results as you can't upconvert SD to HD and achieve HD quality.

For example my dad had a tape of some film and he asked me to put it to DVD. While I have the gear and the capture to better than SD it can't replace the lost quality. I did the transfer and ordered the new DVD which I packed into the shipment.

The word is he tossed the old tape and conversion.
