First I wanted to say nice work with the Windows build script! I just built this under Windows 7 64-bit natively and everything I've tried so far (recording playback) works great. There were two things that I wanted to note though: 

1) The Git tool installed to C:\Program Files (x86)\Git but the script was hard coded to look at C:\Program Files\Git. A quick update to the script fixed it (I don't know how to generate patches). 

2) The mythfrontend application was found under C:\MinGW\msys\1.0\home\<user>\mythbuildw32\mythinstall\win32 not C:\MinGW\msys\1.0\home\<user>\mythbuild\win32\mythfrontend 

Build time was overnight (I think 16+ hours) on my Intel C2D T5800 @ 2GHz laptop. I haven't tested it extensively yet but so far so good! Keep up the great work. 

Kind regards,
