Hello Eric,
Currently I am working on making AbelCam less CPU intensive.
In order to achieve that, I will use a different video capture library, and so far, that one does not support WMV at all.
At the short run, nothing will change.
Within a few months, there should be a camera interface which is putting less load on the computer.
Within a year or so, I will probably have the new interfaces functionality to match the current one, and probably WMV9 (or maybe 10 by that time
) will hopefully be implemented.
