I have been trying to backup my copy of "Ladder 49" and so far I have been unsuccessful using every DVD-ripper I possess. Even AnyDVD is having problems reading the disc and then after a while it will display info on the disc. On this and several backups I have had trouble at VTS_01_4.VOB. What is the matter? I have a LITEON 851S drive GSOP and now I seem to be having problems on certain backups. How can I determine is I have a drive problem related to Region code, the drive is showing Region 1 in Device Manager. Can I get some help please. Thanks.
