Creating DVDs is an art that takes much practice (and frustration ). I don't know if WMP will even burn DVDs. I've never tried. I've only used it to burn CDs. You could try Nero. That's what I use. It comes with a free trial and will burn DVDs.

Before you burn your DVD, however, have you checked the quality of the movie you created? Many simple programs (I'm not familiar with XviD2DVD) don't output very good quality (for my taste). If it doesn't look good on your computer, it won't look good on your T.V.!

Good Luck
