UDF 2.01 on Linux

Mounting DVDs created by Windows Vista with UDF 2.01 or 2.50 filesystem

While UDF 2.01 filesystems created with mkudffs work fine with Linux, UDF media created on different platforms may cause a lot of trouble.

To make Vista UDF DVDs work with Linux, you'll need to patch your kernel with the following patches to your 2.6.24 kernel:

• UDF 2.50 patch for linux 2.6.24
• Now you just have to apply my little patch to make things groovy:
