[mythtv] coreavc patch for mythtv on amd64 architecture

[Markus Frahm]

Hi, i cannot compile libdshowloader on an amd64 architecture. Is this not 
possible? I would like to have coreavc support to be able to see HDTV (H264 
PAFF) content.
I think it has something to do with an old wine version (and therfore old 
includes, which are not supporting x64 architecture) which you are using in 
this patch. Am I right?

 I get the following error: In file included from wine/winbase.h:5, 
 from win32.h:13, from driver.c:19: 
 wine/winnt.h:626:2: error: #error You need to define a CONTEXT for your CPU

Would be great if you could help me.
