You complicate things too much but I understand if you didn't work a lot with flash.
Don't touch left buttons or progressbar clips.
Work only inside right buttons clip.
Once you make a room for logo button, reposition buttons inside right buttons as you want it to be displayed.
Don't look if right buttons exceeds flash scene.
Once right buttons finished, set HD button, right buttons and right sizing button with your choosen intervals.
Don't worry if controlbar exceeds scene or right buttons overlap progressbar.
I've made test skin based on daily skin with NV picture icon as a logo button placed before fullscreen button, it works as expected, also goes to URL on click as I described above.
Always best is to work on examples, so here you have fla source:

Imagine this: Nuevoplayer was the very first flash application I ever wrote in my life. And It was huge success.
But previous experience in programming helped me a lot. It's long experience, started from programming 8-bit assembler on old 8-bit commodore and atari computers, many years ago, about 20.
