Hi,

I have sent some mp4 video files to my friend by e-mail. But few of them playing on his computer most of them not playing. Showing that file may not be supported to wmp. He couldn't open the files using real player, wmp. Even he has new windows7 laptop. All files are still playing on my laptop.
Please let me know to solve this problem.

Thanks

Get him to download and install this: VideoLAN - Official page for VLC media player, the Open Source video framework!

Thanks for your reply.
Same things are happening on Vlc player, real player & wmp player.

Looks like they may have got corrupted during the sending. Try zipping them and sending the zip file.

I will try that. Anyway thanks for your promptly reply.
