Bluray drive won't recognize Bluray discs. (solved)

[sumawo13]

I purchased a Bluray reader and DVD/CD burner combo drive and The Dark Knight on Bluray with the intention of decrypting it and encoding but my drive won't recognize the disc. I even have a Bluray disc which came with the drive with software that can't be recognized. It recognizes my DVD version of The Dark Knight fine.

I'm using Windows XP Service Pack 2. Do I need Service Pack 3 or Vista for Bluray?

What do you mean your drive won't recognize the disk? Do you mean if you open My Computer and double click on the drive, you don't see any files? This is because you need to install a UDF 2.5 driver. Just run a google search and you will be okay.

Yes I wasn't seeing files, it told me there was no disc in the drive. Also your solution worked, thank you.
