Bewildering CloneDVD error

[Sovin _Ndore]

Okay, maybe someone can tell me what is going on. I started Clone DVD and selected the VIDEO_TS directory. This is what I got in response:

Clone DVD 1.3.9.8 error message:

Unable to open video files
Error opening video files from
D:\VIDEO_TS
DVDManager 5 1 IFOFormat 15
[Okay]

My D: drive is a PHILIPS DVD+RW-D28 that came packaged with my Dell Dimension 8200. I have had no driver issues to date, and the particular DVD runs fine off of this drive through PowerDVD 4.0.11 and on my stand alone DVD player. I am also running AnyDVD 2.0.0.4.

What I know about the disk. This disc is not proprietary and was made by a local church. Therefore I should have no issues with protection schemes. The Disk only contains a VIDEO_TS folder, and that contains the following files:

VIDEO_TS.BUP 12 KB
VIDEO_TS.IFO 12 KB
VIDEO_TS.VOB 36 KB
VTS_01_0.BUP 78 KB
VTS_01_0.IFO 78 KB
VTS_01_1.VOB 1,048,018 KB
VTS_01_2.VOB 1,048,018 KB
VTS_01_3.VOB 1,048,018 KB
VTS_01_4.VOB 1,048,018 KB
VTS_01_5.VOB 11,746 KB

SmartRipper had no problem whatsoever with the disk under the same conditions.

Could someone please help explain.
