Need help downloading DVD data

I have a 4 yr old laptop with a CD writer, no DVD writer. It has usb-1 ports. I need to download mapping data from a DVD for my GPS. I don’t wish to buy an external DVD writer at this time. I have access to a desk top PC with a DVD writer. It probably has usb-2 ports. I don’t know if these kinds of ports are compatable with each other. Is there a way to play the DVD on the PC and patch it to my laptop for storage of the data?
Thank you,
John
