I've placed a QT video on my site, but the player/progress bar at the bottom is slightly sunken and you can only see roughly half of it.

Perhaps it's best explained by looking at it:

Any ideas on how to get all of the bar to appear?

at a guess, did you add 16 pixels to the height for the controller?

ie: your source code says

<embed src="movies/lon_assembly.mov" width="600" height="338" blah blah blah>

try changing height to 354... that may solve the problem.

Great guess Rob, you were on the money.

Thanks for that, I didn't realise I had to add additional space.

Do you know that your music is "left channel only" on the clip you posted?

I didn't! Thanks for letting me know. I'll check it out.
