Does anyone know if there is a way to embed flash transparent

active-x control?
Possibly, but I'd hesitate anyway. I think the Windows Media Player,
implemented as an ActiveX Control, also has support for rendering to the
browser's compositing buffer via WMODE requests, rather than blasting
directly to screen. Just as DHTML cannot layer above SWF unless the SWF
is routed to the browser's drawing buffer via WMODE, the WMP would need
to go into the browser's buffer to layer anything atop it.
But I'd hesitate to do so, though, because drawing video offscreen
before transferring it to the video display would give a performance
hit, and you'd also likely drop frames from timing differences too...
the video codec renders every X milliseconds, the browser refreshes its
display every Y milliseconds, and some info would be lost in the middle.
Steven Sacks has info on the scrolling issues too.
If you must use WMP (for rights-management, eg), then could you keep it
drawing directly to screen, and surround the WMP with with four framing
SWFs, intercommunicating through LocalConnection? This would be a little
more development work, but would make less work for the browser's
rendering pipeline. Possible...?

Browser differences are browser differences. When WMODE is changed, then
the Player changes the address in memory to which it sends its pixels.
Over the past eight years the Player has implemented WMODE requests,
we've seen different browsers print upside down, not pass screenreader
instructions, do funny things with keyboard entry, when the browser gets
in the middle of the rendering pipeline like this.
The Player is the same across environments, but it's the environments
themselves which differ, and when we ask the browsers to do more, their
results vary more.
