Re: "Windows Media Player Encountered a problem while playing..."
When you install a third-party product that registers its own version of the Wmp.dll file on a Windows Vista-based computer. Windows Media Player stops responding. To fix this problem for you, go to the “Fix it for me” section. If you prefer to fix this problem yourself, go to the “Let me fix it myself” section here - http://go.microsoft.com/?linkid=9657451

Get Windows Media Player 12 in your system. This is the new version and is better if you are going for a live streaming work. Due to upgraded version you get a better media player with many features. There are ample of bug fixes in this version also. Windows Media Player 12 comes with easy media streaming option. You just required to share the media folder via it and done.

Re: Windows Media Player encountered a problem while playing the file.
There can be cases where media file are corrupted or are unreadable by Windows Media Player because of which you are getting that error. So it is recommended that first you check the files are proper or not. Convert them mp4 if possible with a good convertor. There are certain convertor which can enhance the quality of existing media and make the streaming much more better like VLC. It is not a compulsion to use Windows Media Player only.
Re: "Windows Media Player Encountered a problem while playing..."
I had gone through those replies. I faced a similar issue some month before when I was also using Windows Media Player 11. After upgrading to Windows Media Player 12 I found this more beneficial and better to use. Adding additional type of codec allows you to have multiple options to play media files. Keep your system upto date always to find proper updates to avoid such issues.
