PocketMatrix

I am a beginner.
PPC use windows mobile 5.0
I used the project in the File of GledPlay.
GledPlay->projects->Single State Game Template->WM2005

add
if(video.open(TEXT("001.mpg"))==ReturnCode::OK)
{//Ok, ready to decode.}
else{shutdown();}
to
InitialApplication::onInit(Surface* pBackBuffer, Application* application)
add
HRESULT hr = video.getNextFrame(&surface);
switch(hr){case ReturnCode::OK:pBackBuffer->bltFast(0, 0, &surface); break;
case ReturnCode::END_OF_VIDEO:shutdown(); break;
default:shutdown(); break;}
to
InitialApplication::onNextFrame(Surface* pBackBuffer, Panel* panel)

Just all!

I can't find CEUX in MSDN.
Can you explain it to me?
Thanks!
