I downloaded media player classic the other day, unpacked it today to watch a mp4 video that I downloaded from:
I have a vista computer. The mp4 files are around 105 mb. I drag and drop the file into the mpc screen, and it immediately minimizes the screen, and plays the audio part. I can hear the audio but no video is shown.
I previously saw these mp4 videos shown on real player, but I do not want realplayer.
I searched the forum using combinations of the words mp4, video, and vista, but cannot find any posts.
Do you have the codecs necessary to play the file? You should download both QuickTime Alternative Lite (http://www.codecsdownload.com/download/QuickTime_Alternative.htm) and Real Alternative Lite (http://www.codecsdownload.com/download/Real_Alternative.htm) and see if you can play mp4 files afterwards. Usually just having these two codecs along with the ffdshow codec one can play pretty much any file with Media Player Classic.
