Unless your models have weird drivers you absolutely can have multiple disc drives

Do you want to keep the original file size or reduce it?

It’s possible to compress with minimal quality loss by transcoding (since you can switch from the old inefficient DVD codec to a modern one). But just ripping the ISO image of the disc is the easiest thing you can do and it preserves the original perfectly, so if you have enough disc space you could start with that and maybe compress later if you start to run out of space

That works well if you’re OK with using default options, not very user friendly the second you want to tweak stuff.
