Hi!
My cineform Aspect HD testing period has just ended, i deleted it and found out that i can't play any of my encoded/ripped videos anymore (24fps).
I use GomPlayer and Mediaplayer classic...which were perfectly playing those files...not now anymore.

What is the big deal?

Get the Cineform NEO player and you should be okay again:

After all, your files are still encoded with the Cineform codec.
