When using AVS DVD Authoring, the software created the initial files (.vob) which are supposed to be written to the DVD. When the "write" phase of the process begins, I receive the following error:
Class not registered ClassID: 5133E467-4331-433E-A43C-C36859385531.

My system is an ACER 4810T-8480 Intel Core 2 Solo processor (SU3500 1.4GHz, 800 MHz FSB), 4GB DDR3 RAM.

The DVD/CD-ROM is the HL-DT-ST DVDRAM GU10N.

My OS is Windows 7.

The version of of AVS DVD Authoring is 1.3.4.56.

I ran "regedit" and did NOT find the ClassID listed above.

When I ran the AVS Repair, all Library's were "success" EXCEPT the AVSMobileDevice2ActiveSync.dll. It doesn't look like that could be the problem.

Any help is most appreciated.
