Dear David,
Thank you for responding to this post. You've answered a question for me that I hadn't yet asked!
I have an application which uses wxMediaCtrl to playback video files, and I tried using screen cast software to create a Flash demonstration of it. The software worked well for capturing everything except for the video playback. The best that I could achieve was a single capture of the last video frame, but mostly the wxMediaCtrl simply remained black. I tried different software and different video formats, and tried them also on other video playback software with the same negative result. After reading your reply, I switched off my video card's hardware acceleration, and now I am able to also capture video playback in my screen cast.
Thanks for your advice!!!
Best regards,
Tim
P.S. The Screen Cast software which I'm using is called Wink; from DebugMode Wink . It seems to work well and its freeware.

Can I take a screenshot? Should I use same method as when taking screenshot of widget? (AFAIK it won't work with Xv output in X11).
Screen shots of video are often problematic. To optimize throughput, some
video players (or is it video cards) do funky things like writing to the
screen directly, bypassing certain OS levels. This causes problems with a
lot of screen shot methodologies. On Windows, I usually have to turn off
hardware acceleration on my video card to be able to get a screen shot that
includes video. On Mac, I don't have the same problem. I don't use Linux
enough to talk about that.David
