fraps broke

When recording video from a game, fraps records only audio, Windows perceives .avi video from fraps as an audio file. Moreover, the fraps was already configured and used for six months. Reinstallation did not help, only it saves the bandits because there you can select the mp4 file and only then the video turns out if you select Avi then there will be sound. Save because fraps does not load the computer as much as it does to bandits.
