I captured some videos with Nero 7 which does so only in mp4 format. But WMP
11 does not recognize the file format as a Media file. I thought Microsoft's
wmv format itself was mpeg-4 and WMP 11 plays wmv files. Is mp4 different
from wmv format?

But if I ask WMP to open all the files in the folder, it opens the mp4 file
and even plays it. So why does WMP not recognize it as a Media File right
in the beginning?
