title: How to play mp4 videos using MCI device
body: <p>Using the  mciSendString command I am able to play avi, mpeg, mp3, etc. but I am unable to play mp4. Here in this <a href="http://www.vbforfree.com/?p=402" rel="nofollow">web-site</a> it says I can play any videos provided that I have the correct codecs. I am able to play mp4 using my other media players (eg. vlc player). How can I play mp4 videos or how can I make the MCI device auto detect the necessary driver type and play the videos ?</p>
