One more time...
Below (I hope) is a link to an image which will illustrate what I am trying to get across. Note that the only difference between the two video snapshots is that in the first there are black borders on the sides and in the second there are no black borders. The video is not cropped or distorted in any way. None of the source video is missing. All that is being displayed is what the user wants to see - the title bar and the video, uncropped and scaled to fit the window (in the correct aspect ratio).

I am reminded of a TV show from the 70s where a mother was upset when she discovers that the boy her daughter is serious about has parents who are midgets (the boy is normal sized). She tries to explain to a coworker why she is upset by saying "Bess wants to marry a boy whose parents are midgets". His response is "Has she found one yet?"
It continues...
"Bess HAS a boyfriend and her parents ARE midgets"
"Then What's the problem?"
"The problem is she's too young."
"How old do you have to be to marry a midget?"
"She's not marrying a midget."
"Poor kid. She wanted to so badly."
"The boy is not midget. His parents are."
"If she wants to marry a midget she should hold out for the real thing."
It goes on this way for several minutes. In this case, the mother has not considered what language she needs to use in order to explain it to a familiar coworker. In my case, not knowing anything about you, I don't know how to tailor my explanation to my target audience. Obviously I am failing to get my point across.
If the link to the image I posted does not work please tell me how I can post the image here as it seems to be the only way to illustrate what I mean.
