Hi,
I have both VistaCodecs_v473 and x64Components_v152 installed on Vista Ultimate x64.
I am using this .reg file for my .mts video files (AVCHD)

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.mts\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{c5a40261-cd64-4ccf-84cb-c394da41d590}"

I am unable to see thumbnails, just an icon that looks like the filmstrip and "MPEG" below (see attachment).

I have reinstalled VistaCodecs both main install and x64 components.

My registry entry for .mts lists (Value Not Set) for the main .mts key, I have seen on others it lists WMP11 and video as type.

Not sure what actually renders the thumbs for these .mts / .MTS files but would really like to figure this out, I am going nuts trying to get it working.
All of my MPG and AVI render thumbs perfectly, it is just the AVCHD ones.

One thing to mention, it worked great when I first installed VideoCodecs, but after installing VLC Media Player and Nero Lite something got screwed up (my doing), just not sure what or how to fix...

Thank you for any thoughts, I really like VideoCodecs and plan to donate, It is a great package...

OK, dear, I think u can try 2 import this for addition~

Hi, thank you, that was already in the reg key, did not help unfortunately.

Thank you for the idea...wondering if anyone else has thoughts?
