I downloaded a video of a game trailer after waiting for a long time as my internet was slow. Then after downloading I saw that the file always shows an error in media players, when I checked the file, it didn't have any codec. Generally, playable media has codecs like (A:mp3, V:Xvid) while the intro I downloaded was empty (A: , V: ). I waited a long time to get that intro and I'm not willing to download it again. I've also tried converting this intro from video converters but they say "The file selected is not an audio or video file". How do I fix this?

~Thanks!
