How can I watch a movie in mdf format in my PC? I have realplayer, window media player and quick time player.
Please help! Thanks.

install Alcohol 120%, mount the mdf file to it, and you can use windows media player to see it.

Thanks for your advice as I was able to view the mdf movie in window media player after mounting by Alcohol 120%. However, I have another problem: how can I share the movie with my friend if she does not want to install Alcohol 120%? That is, is it possible to convert the mounted movie into other format so it can be viewed in window media player or real player? Thanks!!!

use Alcohol 120% burn the cd or dvd

Is it a VCD or DVD?

you can use Alcohol 120% to burn the mdf file to CDs, your mdf file should be a VCD format, so after you can even play the disc on dvd player.  If you mount the file to the drive, you can just copy all the data from that drive to your hard drive.

you can use nero7 nero show time to see in ur computer dont need copy VCD or DVD ga

其實只要用虛擬光盤載入就ok，Alcohol 120%和Daemon Tools都可以。
然後你就可以在你的電腦上打開mdf。
