Powerpoint 2010 - cannot insert video - need necessary 64-bit codec

I want to insert a video into ppt, but i keep getting the message "power point cannot insert a video from the selected file. Verify that the necessary 63-bit codec for this media format is installed, and then try again."

Can someone point me in the direction of the correct codec?

I have a video converter and when i convert it to wmv i lose quality, i want to use a figher format but ppt doesnt support anything
