I have various files, mpg, avi, mov, flv, divx, xvid.

I have a dvd player that can play all types of files, so I can just create a data disc and it will play those files on the disc.

However other players that are older aren't able to play those files, and it has to be an iso image or traditional dvd. So I have to create the disc differently. I would have to convert the file to a different type then burn it through another program that creates dvd's and that whole process can take 3 hours. As is, some that I try, where the file is 1.3-1.5gigs, the program says it doesn't have enough temp space on a 4.7 disc for some weird reason.

What is a good program or the easiest way to convert various media files to an iso image to be a dvd that can play on older dvd players?
