"Cars" is released 2 versions. One has RipGuard, another has no RipGuard. I bought no-RipGurd version and now can find and buy RipGuard-version, and become to be able to compare. They have no difference exept for RipGuard. About no-RipGuard version, I experienced the problem of RipIt4Me and DVDFabDecrypter(PathPlayer). They remove playable cell which is well-known as Easter Egg. I found the reason is they can't recognize button command which in 2nd set of multiple sets. AnyDVD has no problem about it. But about RipGuard version, AnyDVD seems to have same problem. There is no preblem if AI Scanner is off. I thought strange it from zip file, that AI Scanner seems not to work about no-RipGuard version even if AI Scanner is on. Here is zip files. drive I => RipGuard version drive K => no-RipGuard version Regards.
