To sidestep all that, I installed the following. I'll share the prices I paid too.

1. USB 2.0 PC-Card 39 dollars.
2. USB 2.0 DVD/CD enclosure 45 dollars.
3. 4X DVD all format recorder. Sale at 79 dollars. Included software.

With that I can edit then create the DVD on either DVD-R or DVD+R media. I currently use DVD+R/W for test media since my DVD player plays that.
