Winff will convert a file from some format to some other format.

If you begin with a video tape, you will need video capture hardware.

DVDs can be PAL or NTSC. For DVD creation, I prefer Devede; spend 20 minutes
perusing the excellent help file before making any DVDs.

Wouldn't you just capture while playing from the TV/monitor?
