Q: Why is sound only coming out of One Speaker (Left or Right Channel) when I use Sony Movie Studio or Sony Vegas Pro ?

Answer: In Vegas you should check the PAN slider for each Audio Track - this controls the stereo nature and should be in the middle position by default. If you have accidentally moved the slider for Pan Controls, sound will ONLY come out of ONE speaker.

Strange Video Codecs

Another problem can come from the type of video you import into Vegas, which may be a strange codec that Vegas cannot decode properly.
