Answer 1

Ok, i have to capture image from tv tuner card. of course, i need to get proper resolution of the captured video (720x576)

i tryed to create my own application with next code:

http://www.codeproject.com/KB/directx/directxcapture.aspx

but, with that code, image quality is more than poor. it looks like it is 320x240 or something.

can you help me by giving some clue, where can be a problem? looks like i can not change resolution of video?!

please help!

and something more... i did try with SampleGrabberNET:

codeproject.com/KB/directx/directshownet.aspx

... but, if i setup 720x576, program crashes...

please, please, please, help!
