Hello guys,

I have downloaded some dance vedios from the internet. Then I tried to open them in Windows Media Player on Win 8, but it told me that mp4 were not supported in this player. Then I converted them into AVI, they could be played on my computer, while it was a failure after I transfered them to my colleague through gooletalk.

Do you know what the matter is?

Thanks a lot!

hi Hongmay,

which edition of Media Player are you using?

You are most likely missing codecs. You could check the microsoft media player web site and download the needed codec there and addon to the media player as well.
