Well, I tested it on two machines with XP SP3. Simply dont works with Emumovies MP4!!! I tested folders tips, reinstall codecs... but nothing changes.
So, I install Mgalaxy in Win 7 32 and it works fine!
What's mean that Mgalaxy play the videos? Some codec special? A external player?
I reinstall Klite Megacodec, but in XP it still dont works.
