Seriously, can you provide, as i asked before, the registry paths i should be looking into (and what values they should be after BD-RB intervention ?) so at least i can start debugging something ?

A warning to all -- if you are not careful you can screw yourself permanently by messing with the registry -- and you're on your own when that happens. I take no responsibility for any actions you take in editing the registry.

@PhilippeB
For your problem it appears that there are some keys that should be set but are not.


In this registry area:
HKLM\Software\Microsoft\Directshow\Preferred

These keys:

{31435657-0000-0010-8000-00AA00389B71}
{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
