Some months ago I bought a Hitachi DZ-HS500E - and am still experimenting !!! but I noticed that the sound quality is distorted, I thought it was "me" but I recently filmed the Red Arrows and the noise even on playback through the camera is horrendous. I know it must be magnified by the aircraft noise, but can you tell me if this is likely to be a hardware problem necessitating a return to Hitachi - before I box it up and send it back whence it came !! I hate to look an eejit if there is a setting I missed. !!!
