How can i turn a retail DVD disc game, into and .iso so i can patch it with a fix?

I am not sure but aren't iso's required when you are burning a game to a dvd. I have heard of several people having problems putting this game on there harddrives. From the best I can tell it has to do with the length of the file names and evox having trouble with it.

I also heard of people having no trouble as well so I guess it's hard to really say right now what is going on so I am just waiting for someone to figure it out.
