I guess I didn't explain well enough.
I was looking for a solution to make copies of the games to the DVD-R's. My initial post was mentioning I had an issue with my main computer, and I posted the error.
Then I decided to try it on my gf's computer which is right next to mine, and it works.
So basically, at this point, my question is, what do you think the issue with my main computer is, based on the error message above?
Thanks for taking a look.
( i have however, been able to at least make the copies and verified they work in the wii, i just have to use my gf's computer, unless I find the fix here)
