I have testet cineform AspectHD for 15 days. Remove it. But when opening windows mediaplayer i got this CFHD.dll error from Cineform.
Who to delete all of this cineform from my computer?

It looks to me like your CineForm VFW codec has not been uninstalled.

These are the instructions I received for manually uninstalling everything to do with Connect HD. For the problems you are having, they should work for Aspect HD too. But basically, that DLL file you are having problems with resides in c:\Windows\System32

Uninstall Connect HD

Remove 'CineForm HD VFW Codec' from Add/Remove Programs

Check C:\Program Files to see if there is a 'CineForm' directory present. If there is, delete it.

Check C:\Program Files\Common Files to see if a 'CineForm' or 'Moonlight' directory is present. If either of them are there, delete them.

Check C:\Windows\System32 to see if two files are present, "CFHD.dll", "CHFD.inf". If either of them are there, delete them.

Click on the 'Start' button

Select 'Run'

Type 'regedit' and click 'Ok'

Open 'Hkey_Local_Machine'

Under ‘Heky_Local_Machine’ open 'Software'

If a 'CineForm' folder is present, delete it.

Open 'Hkey_Current_User'

Under ‘Hkey_Current_User’ open 'Software'

If you see a 'CineForm' folder, delete it.
