Problems with toolbar viewing full-screen video.

I posted a 720x480 video here:

When I play it back in full-screen mode on my 1680x1050 monitor, it fills the screen beautifully. However, the control bar at the bottom doesn't respond properly. It doesn't pop up when I mouse over it, at least not right away, and when it does pop up, it slides back down before I can click the button to exit full screen mode, even if the mouse pointer is moving across the control bar at the time.

The upshot is that once I launch the video into full-screen mode, I have to watch it to completion in full-screen mode, which is kind of annoying.

Anybody else have this problem? Any ideas?

Here's a screen capture of the behavior with a slightly-different earlier version of the video:

Hi, details on browser? :ear

Hi, details on browser? :ear

IE 7.0.5730.13
Adobe Flash Player 9.0.124.0
QuickTime Player 7.5(861)
Windows XP SP2 & SP3 (just upgraded)

Just testing it a little more, I notice that in full-screen mode, Task Manager shows about 75% CPU across all four cores. It's not a slow computer, but the graphics card isn't a super-fast gaming card. Maybe I'm just pushing the system too much, but shouldn't it be the video that gets bad rather than the user interface?

Anyone? Anyone?

Hi we cannot replicate :( Still trying.

Eh, and nobody else has mentioned it.

Maybe something on my computer is misconfigured.

Thanks.

Is the video playing just as smoothly as when in non-full-screen mode? If not, your CPU is probably not fast enough to process everything.

It's very smooth in non-full-screen mode, and the menus work right.

My computer is a quad-core 2.66 GHz Intel Core 2, and all four processors are at about 75% in full-screen mode. If it is a hardware performance problem, it can't be the CPU, or the cores would all be pegged at 100%. My guess would be that it's a memory bandwidth issue.

Painting that size screen with 30 frames per second of 32-bit color requires a 200 Mb/second transfer. I would think some of that could be offloaded to the video card by letting it do the resizing, but I don't really know how these things work.

In any case, I would hope that Flash and/or Quicktime would deal with the resource management issue and keep the user interface responsive. Since no one else is seeing a problem, maybe it's just my computer. That's actually good news, because it means that my visitors are getting a quality experience.

If the video is not playing just as smoothly as when in non-full-screen mode then your CPU is probably not fast enough to process everything, even if it is only showing 75%. There can always be software issues as to why an application can't use 100%. One suggestion would be to try to change the color resolution to 15 or 16-bit. I'd even try 256 colors for testing purposes and see if that changes it.
