You could try ripping the dvd to sd using a ripping program like dvd decrypter (old outdated software but free) or try a trial version of Anydvd that allow you to rip the dvd to hdd (21 day free trial but it's expensive).
Be aware that unless your SD card is formatted to ntfs you'll be limited to a dvd file of <4GB unless you shrink the file size to be within the file limit.
