Trouble Listening to .MP4




I have a sound alert that I shared with myself via email. I receive an error when trying to listen to it with either Windows Media Player or Quicktime. The error message states an invalid sample description. Any ideas?

Thank you


Use VLC (it is free), should be able to play pretty much anything.



Thank you. I just downloaded the VLC media player. It worked like a champ. Appreciate the tip!
