can not play *.mp4 movies


Recommended Posts

I too have recently noted that mp4 files won't play.

I have tried uninstalling mpcstar and then re-installing it with no difference.

This situation has only started in the past few days (2 minimum, 7 maximum).

If there is any additional information that I can provide in order to try to get this situation resolved, I will provide it as soon as I am able.

My testing, so far, shows that this issue only lies with mp4 files. While I could convert them to AVI, which does work correctly, I really don't want to spend the time as I have quite a few mp4 files.

I've been having the same problem! All of a sudden every *.mp4 or *.m4v (itunes) file that I play will show picture but no sound.

At first I thought the problem was with my computer until I discovered that it only happened with those 2 extensions. I finally tried converting a video to *.avi with FileFormat, which solved the problem, but to convert all of my .mp4 files would take forever.

Nothing has been installed, updated, or downloaded onto my computer in 2 weeks so I can't understand what happened.
