Do dvd "programs" let you copy to a cd?

Do some, most or all dvd down loaded copy programs let you copy the program first to a file so then I can burn the program to a cd which will let me do a reinstall should I have a crash or change computers?
Do copy programs let you burn more than one (of the same movie)
Hope im in the right forms for the questions, if not please direct me. Thanks

For your 1st question you can just drag & drop your install files for any type of downloaded program (or use something like neroburn to burn a data cd)

Most if not all dvd backup programs will allow you to burn more than 1 copy
