If I start a video while XBMC is windowed, DXVA is used and continues to be used if I maximize the video with the '\' key. However, if I start the video while maximized, I do not get DXVA support. Screen shots are below.

According to my experience, for DXVA to work with XBMC-DSplayer + SVP you need to check "Use fullscreen window rather than true fullscreen" option in XBMC settings. In true fullscreen (screen exclusive mode) XBMC-DSplayer + SVP + DXVA does not work.

That fixed it on my other system!!!
I'm still bewildered why it works OK on my newer system without having to do that. But sometimes it's enough to just get it to work.
Thank you!
