xlv600 is an unknown quantity at this point

No overlay means that all overlay modes or left unchecked, is it that complicate?

In overlay mode, the picture is directly written in the video card memory, this is a write only process, so that no application can read it back.
I just tested the feature on one movie in full screen with no overlay and with Shift+P I got a 1280x533 JPG. [Alt+3] tells me it's a 576x240 DivX3 movie (that use YV12 surface).

PS: Maybe it doesn't work on every movies.
For instance I had to check Use-VMR9 to be able to take a screeshot of a DivX5 movie wich surface was "Unknown". Then I could only get a BMP and of the original size.
You have to make you own investigation and test on several movies. I thing that the main concern is the surface used for encoding the video.

TIP: When no overlay is selected, then you can use the [PrtScr] key to take a screenshot or [Alt+PrtScr] to restrict to current window. And paste the picture in your favorite photo editor. If in full screen, you'll have to crop the picture as black stripes will be included.[/i]
