DVD Distorted Audio?

Hey Guys. I am trying to deal; with this problem but I just have no idea what to do...

I produced a piece for a regular client of mine. It consists of music only, no speech. I rendered to MPEG-2 for DVD with 256KB PCM audio. Burned with DVD Architect 2 and ran fine on both my Onkyo DVD players with Imation Business Select media (Hi-Grade).

He took it home and ran it on a Sansui DVD player and noticed that the audio was shockingly distorted and lound. He then ran it on a new JVC player and had the same problem just this time the video froze. There was no menu on this DVD.

On a past presentation I did for him I used Verbatim media with Dolby Digital Stereo 192KB. This ran perectly on both players!

Is my problem the media or encoding. I couldn't understand that it was either as I have been using this process for ages with so many clients...?

Any insight would be great. Thanks!

It's likely the encoding, that there is no normalization flag set with PCM, it could be that his system is reading it as 5.1 surround vs stereo, due to a bad flag or due to a glitch, or....At 256kpbs, you're pretty low quality...for a .wav file.

Thanks spot. Just how would I set no0rmalization using Vegas?

Thanks

When you render your AC3 file in Vegas, click the Custom Tab. You'll see the normalization settings in there. I'm rendering in the background on this system, so can't open it just now to recall the exact tab, someone will chime in. I've just always got mine set to a Vegas preset now, never even look any more. I'd render some short experiments with a section you KNOW is distorting on their playback system, make some test files.

I believe what Spot is referring to are the following settings (saved from a post here some time ago).

Encode set to AC3 .
Click on custom tab .
Dialog normalization: -31 dB.
On the first tab set diag. norm to" -31" .
On the last tab marked preprocessing, set the line profile mode set to "none" .
Now save that as a preset.
