If a DVD is mastered as multi-border or multi-session in Microsoft Windows 2000 and in Microsoft Windows XP, only the first border can be read.
This problem occurs when there is more that 4 gigabytes (GB) of data in any combination of borders.
The problem is caused by a rounding error in the UDF reader (Udfs.sys).
