Help with Analog Audio Quality on DVD
I recently edited some 8 mm mono analog videos in Vegas 7 and have an issue with the audio quality when I render it out to DVD. The videos are of friends of mine interviewing their elderly parents about their lifetime memories. In some areas I added stereo music as background music under some of the dialog. I used volume envelopes to increase the volume of their parents weaker voices and several different audio filters to reduce background noise. The level was 6-12 dB. I set background music to a lower level so as not to conflict with their voices (18-24 dB). The quality and balance sounded fine on the timelime. ( I have a 5.1 Surround Sound system on my PC.) I then rendered it to MPEG-2 and Dolby Digital AC-3 and burned it to DVD. The audio quality also sounded fine on my TV but I do have a 5.1 surround sound system on it as well. However, when I played the DVD on another TV that required that the audio play through the TV speakers the quality was noticeably reduced. The dialog was muffled and additional background noises seem to appear. The background music volume was too loud and somewhat blaring. My friend even complained about the music being too loud over the dialog. I expect a quality reduction because of the change to TV speakers but there seems to be more going on here. How can I remedy this without having to do hours of trial and error renderings to improve the audio quality and volume balance between the dialog and background music? Should I render all the audio to mono? Should I render it uncompressed? Is there a different way to render it that won

On the Surround Sound Mixer, there is a button (to the left of Dim Output) to Downmix Output. That will let you hear your project in stereo.

Gary,
I had the master bus set to stereo to begin with and rendered it that way and not as surround sound.
