I have a project that I have mixed as 5.1 surround since I originally thought I was going to go out to SD DVD. However, as the original source material is HDV video, I'm now trying to render as HDV using the HDV 1080 60i template in Vegas 7. But - perhaps not surprisingly - the volume on my two rear channels of the mix comes out very low - too low for my purposes. Clearly the audio portion of the HDV template doesn't support 5.1. Any ideas how I can maintain my current audio mix and output as HDV?
