I used to have K-lite pack on my computer and replaced it with ffdshow. K-lite has a program that would scan a video file and tell you what was the video format and audio format and if you had the required codec installed. I think it was GSPOT, but I am not sure.
Any suggestions for a similar program, or if I can install the original program that was with k-lite without interfering with the ffdshow application. Thanks.
