Could you pls do the following and report back assuming you have a DVD ROM on your PC:

1/
List the file details from Windows Explorer to include filename and file sizes and contents of directories

2/
Do a PROPERTIES on the DVD and report back the number of GB stated for the used disk space. This is the TOC.

3/
What size TOC was the DVDR that you booted?

4/
Please display using NOTEPAD.EXE the file called SYSTEM or SYSTEM.CNF. This might also provide the version info.

Thanks
