I am not sure if i understood what problems you are refering to. just to make sure that you know what kind of troubles i have i include a jpeg which shows the statistics (first 3 min.) of the tutorial video (extrude) from Kevin. I do receive all sound but frames from the video are skipped. I do understand that there are several problems with the media player on the mac (guess why?)... maybe this is a stupid question but why not not offer the videos as a quick time movie? THX all for your thoughts and assistance Axel
