Put content on VHS tape to DVD???

I've done that before.
You need a PC video capture card with composite video input and stereo audio input from the VCR, plus good video capture software that can encode into MPG2 for DVD format. You also need a DVD burner drive and media - there are several types: DVD+R,+RW, -R,-RW.
Then you need software that can create the DVD compatable format layout and then software to burn DVDs.

I use an ATI Radeon All-In-Wonder video card that also has video capture and they include ATI software that can capture and encode directly to MPG2 DVD-compatable format. I use TMPGenc DVD authoring software and Nero DVD/CD burning software.

An alternative without a PC is to get a standalone DVD recorder, that works like a VCR and you could connect the line outputs from a VCR to the line inputs on the DVD recorder.
