Dafydd - I'm sorry, I don't know how to provide a screen shot.
Here's a better explanation of what I'm up against.
I am in full feature editor. I have imported an mpeg2 to edit. I see the thumbnail in the library window and the same image in the preview window.
As soon as I drag the thumnail into the first track of the timeline, the preview window goes blank for a second, and then comes up with a green screen (no image). If I hit "play", the range selector moves right, down the timeline. I hear the audio, but only see a green screen - no other inage.
If I click on the "preview in media veiwer" button below the preview window and select "launch media viewer" from the dropdown green preview goes to full screen, still showing only green, and if I hit play, it is still only audio - no image (except green screen). If I hit the red "x" to cancel out - THEN, after a couple seconds, I see the image in the preview window of the editor and it plays image and audio.
Is that the way it is suppose to work?
Thanks.
