Audio problems when Rendered and played back on a TV
It seems that I have better luck in here than the Basics forum (Sorry for the double-post):
Basically what the title says. It all sounds great on my computer, but after I’ve rendered everything and put it together on a DVD- certain TV’s get sound issues. Either it’s too low or a song won’t be playing at all or a voice over won’t be playing at all.
Is there anyway to change the settings before rendering so that it’s an accurate display of what the sound should be?
Thanks

Assuming you’ve gone through your audio before encoding and the levels are all OK, here’s an AC-3 adjustment to make.
Encode set to AC3;
Click on Custom tab;
On the first tab, set Diag. Norm to” -31″;
On the last tab marked Preprocessing, set the Line Mode Profile
and RF Mode Profile mode to “none”;
Save this as a preset. -
Do I understand that it works on some TVs and not on others? Sounds like (oops, pardon the pun) a channels problem. Did you encode the AC3 file from Vegas and did you encode 5.1, stereo or mono?

Sorry I haven’t checked this sooner, I fixed some of the audio by raising it but are you guys saying that I am supposed to render the audio and video files separately so that it doesn’t mess up on a DVD?

The usual recommendation is that you render your video file (MPEG-2) and audio file (AC-3) separately.
As long as you give both files the same surname (myvideo.mpg & myvideo.ac3) and render them to the same folder, DVDA will automatically load the audio once it loads the video.
Depending on the length of the video, you may need to use a bitrate calculator to determine the proper settings.
