I found what caused the above problem. It's antivirus program after all. Norton Internet Security 2007. When I disable Auto-protect, "Beyond Compare" doesn't find any mismatches in files on hard drive and on disc when I do binary comparison, even if I start playing some of the files on disc at the same time.
On my old laptop, I do not have any antivirus in Vista, that's why I did not experience this before. I do have Norton Antvirus 2007 in XP though, and it does not cause any problems.
I think it is still worth if you investigate this issue further. Norton Antivirus / Internet Security are very popular software, and having Auto-protect enabled should not cause errors in AnyDVD's 'on the fly' decryption, IMHO.
Thanks.
