When i download a movie it always comes as just Avi (only sound no video)?
The problems you are describing certainly do sound like you’ve got an issue with codecs on your system. A codec is software that is used to compress or decompress a digital media file, such as a song or video. Codecs are used to create and play nearly all music or video files on your computer or on Websites. The easiest thing to do will be to use a codec tool to figure out exactly what codecs you may need to play the file.

Here’s a handy guide created by Microsoft that explains codecs in a bit more detail, and also gives you some trustworthy sites for downloading them: http://www.microsoft.com/windows/windows… I hope this helps!
