These keys:

{31435641-0000-0010-8000-00AA00389B71}
{e06d8026-db46-11cf-b4d1-00805f6cbbea}

should all be set to

{04FE9017-F873-410E-871E-AB91661A4EF7}

That tells the system that the preferred DirectShow CODEC for VC-1, AVC, and MPEG-2 should be FFDSHOW.

BD-RB looks at these keys when it loads on a Windows 7 system, and tells you when they are incorrect. It then gives you a prompt and attempts to set them correctly. It then looks at them, and if they weren't changed it knows it didn't have privilege to do so, and gives you another "you need to run me as administrator" message.

When it successfully changes them, it also creates a batch file in the BD-RB folder that lets you change them back to their original state.

Note that on Windows 7 64 bit systems the registry path (in REGEDIT) may be:

HKLM\SOFTWARE\Wow6432Node\Microsoft\DirectShow\Preferred
@jdobbs as PhilippeB has said his is a W7 64-bit machine, the entries at issue for him are in the Wow6432Node, not the first mentioned in your post.

I just checked my own 64-bit system and the Wow6432Node entries are all {04FE9017-F873-410E-871E-AB91661A4EF7} but the HKLM\Software\Microsoft\Directshow\Preferred are different. And when I run 0.32.08 (beta) there is no mention or complaint about my system at all.
