In the PDF options, the Play Video in Floating Window box is checked, with the size set to 1x and the Position is set to Center by default but it is grayed out, with no option to change it.
If you have placed the video in InDesign in it's own frame, should you not leave this box unchecked? That PDF control will override your InD layout.
I'm using InDesign CS5.5. You say you're using InDesign CS5.
I tried to replicate your situation by setting up a file the same way you did (thanks for being so thorough about your settings!)
I placed it into InDesign CS5.5 and exported it with Centered selected. When it opened in Acrobat X, it opened centered. That suggests to me that this may have been a bug which was fixed in InDesign CS5.5
Here's how my screen looked:
I ran a test there also using CS5.5 and I was actually able to replicate what you were seeing. Once I clicked the video, it moved away from where I placed it. Turning off those PDF options as I mentioned in my first post corrected it for me.
Edit:// Sorry, I meant to say that I could replicate the video 'moving' issue, however it did go to the center of the screen for me. I placed my movie in different areas of the page and with the PDF options ON, it always moved to the screen center. If I turned them OFF, the video stayed where I placed it.
Thanks for your reply, Steve. I, too, believe there is a bug, but it's not in InDesign CS5, as I mentioned in my post, I was able to replicate the problem by opening the file in CS5.5 and exporting it to an interactive PDF. The movie again opens in the upper right corner.
However, if I create a NEW page in the document and place the same movie. it opens in the PDF reader centered in the page. I guess I could recreate the document if this is the only fix, but I thought that I may be doing something wrong, which apparently is not the case.

Rik, I didn't actually place the movie into a new frame. What I meant to say was that once the movie was placed into the document, I did not resize it. I found that if I don't have the PDF viewer open the movie in a flaoting window, the movie quality suffers if the PDF viewer opens in a larger size than the original InDesign page size (which can happen depending on how the user's PDF viewer is configured). However, the movie plays and views perfectly if it is in a floating window.
Of course, my test was on a new page in a new document, where there was no problem. So it must be a fairly subtle bug, and probably not easy to reproduce. Those kinds of bugs are very hard to eradicate.
I'm having the same problem as Mr. Hartman, in InDesign CS6 with the crux being that *the option to center the floating video is grayed out*. I can't find anything about the placing or the document that changes this. The video always plays in the top right corner.
So the question is, why is the video position choice grayed out?
