Converting Media files to play in a DVD player?



How do I go about converting various media files (ex: avi, windows media, etc) and have them be able to play on a home DVD player, after the burn?

thanks guys,


programs like winavi, procoder express, tmpgenc can do this


do they work for MPG also?


yes, they convert any type of video file to another type


Are there any that are free of charge?
