Greetings,
I just tested your MOV file on my install of CS5 and your export should be fine, if you use a 1920×1080 format out. I used HDTV 1080 MPG2 preset, which I think is where you were going and all looked fine. Change your output preset to a standard one is the only answer I can see. I’m not using German so if you show me a screen of the preset drop down, I can maybe help you select one.
You ARE using the full release of the software, right?
