My windows media player cannot play a movie. it says it needs flv4 codec. what should i do?

Try downloading VLC media player or GOM player.They are free.
You can also try installing either k lite mega codec pack (free) or All-in -One Codec packs.Is it just a problem with this movie??Do you have problems playing other avi files??

What format are the movies?
Try VLC player, it will play almost all formats

Download and install klite codec, it will solve your problem

not sure whether its a problem with the drive or a problem with windows media player. Take a can of air and blow some onto the laser of the dvd drive, this will make sure that there is no dirt or dust on the laser.

Once you do that put the dvd back into the drive. Give it about 20-30 seconds and then see if it tries to pull up the movie if it does and your getting errors from windows media player then we know that the drive is working cause its seeing the movie properly.

At that point, I would suggest downloading the latest version of windows media player.

Go here to download the latest version of Windows Media Player 11.

After doing that and installing it, try playing your movie again, in fact try several movies just to make sure. Windows Media player may want to download Codecs, if it does then let it. This will allow it to recognize dvds better and quicker.

If the codecs are updated and you still can't get it to see and play movies then I would suggest using a different dvd player such as Cyberlink PowerDVD located on this page:

Your media player might be having problems getting the video feed from the USB. try copying the file to your local disk and play the movie from there.

windows media players seem to have a prob. with having all the codec you might need to play a movie. ...even after you install more codec. ....go to the site for VLC media player and download it and you it as a default player. ....vlc media player has all the codec's in it that you would ever come accross. ....works great for me and has never found a movie it could not play

You need a good codec pack. I would suggest KL codec pack full. You can download it for free from here. http://www.codecguide.com/

It will allow you to play just about any video format in windows media player. Note if you are using a 64 bit operating system you need the 64 bit codec pack. Don't forget to rate me.

you can go to divx.com and go to free download, this codec usually has codec for movies

Actually this is a problem of the video codec and you need o install some software that will solve your problem completely.
