[python-win32] How to set value with PyIPropertyStore

[Peng Chen]

Nah, thanks, the stuff I'm trying to do is actually quite simple.
I try to read the "Encoded date" info from video file, apply a timeshift
and write it back.
I searched a few different libs, they are either works for image files only
or it's read only and I can't write.
So I thought of pywin32 and really didn't expect this coming...

Thanks!
