Most pc dvdroms will not even recognise original wii dvd's.
A few lg dvdroms (i have one temporarily) could recognise and read these dvd's but are no longer available at retail.
The only option is a mod chip installed the wii that will allow ripping. you will need to check which modchips supporting ripping and how.
Generally they require ripping to an sd card adapter plugged into a nintendo gamecube port on the wii.
