Hi, if you want to convert movies you have downloaded to a DVD to play on any DVD player ensure you download Movies in AVI format. Then use a program like Convert X To DVD,
VSO Download DVD Burning Software, convert AVI to DVD, video converter, DVD copy to DVD slideshow photo (it does cost to buy but you can download a demo., although there are probably free programes to do the job) I have used this prog for years and it is brilliant at doing AVI - DVD. You can even create a menu. Its other point is its better than Nero as it fixes most Lipsynch problems sometimes encountered in AVI files downloaded, whereas Nero can and often does make it worse.
Hope this helps
