Most of the time I have really no problem w any kind of DVD BUT this 4th series of ALIAS (region2) makes me crazy! CloneDVD sees the correct chapter list only in the 1st DVD but the 2nd and 3rd are not working. All the chapters appear with the length of 0:00 minutes. This reading problem exists even after rebooting w/o AnyDVD. Even a standard media player unable to play the chapters. LG DVD player have no problem with it. Might it be some kind of protection? thanks for answering
