Are there sites that sell video to burn on CD..?

I Know this is probably a stupid question, but…here goes.
Can a DVD be converted or burned to a CD. Also, are there any sites that have CDs movies to burn (for a fee). I have an older Dell laptop, and it has a CD reader only, and I want to watch movies while I fly across the country. Thank you.

What exactly do you mean by “a fee”?

Yes you can convert dvds to vcds (video cd) or svcd (super video cd) The difference is svcd is a higher resolution. Here’s one free tool you can use to convert your dvds to either format. As far as a site so you can DL movies, there are no legal ones that i know of yet.
