I do apologize for my rather bluntly formed question, Daniel (and all the rest of you watching!). Being rather an intuitive problem solver myself i tend to focus on the point i think is the problem, and forget explaining things around it like the program version, codec version, OS and so on. Anyway, i did solve the problem easily by just importing my settings for FFDshow from another program =) So, it was a setting issue, not a codec issue.
Best regards
