Sound doesn't work on home-made DVDs

[NTB]

I believe this is a problem with my HT system, rather than my computer or how I made the DVD - that's why the post is here and not in GH or elsewhere

Anyway, I recieved a new DVD burner for christmas, so I thought I'd try it out with a video I captured using my WinTV capture card. Video works regardless of how the DVD player is connected to the TV (through the reciever or directly connected), but the audio only works when the player is hooked straight to the TV. The only difference is in how the audio is run; when connected straigh to the TV I use the analog left and right outputs on the DVD player. When I have it hooked to the reciever, I'm using the digital coaxial out, instead. Other (store-bought) DVDs work this way though, so I don't know why this would cause a problem.

anybody?

I *might* have figured it out. Apparently, MP2 audio - which is the format the Hauppauge card uses - isn't officially supported for NTSC, but if the DVD player can play VCD or SVCD, it will still play it. So as long as I'm using the DVD player to decode the audio it will work. The coax out just passes the bitstream to the reciever, which can't decode MP2, which is probably why I'm not getting sound. darn. now what?

This could be a mighty dumb reply but did you try recording in Dolby Digital or DTS?

Make sure when you encode the MPEG-2 files that you set it to use PCM sound, and not MP3.

The MP2 audio is my problem I ran a set of analog cables to the L/R inputs on my reciever, and got sound.

Just checked the settings for video capture in WinTV, and MPEG1 Layer 2 (MP2) is the only option for sound. I can convert it to PCM easily enough (that's just .WAV format, after all), but that takes up quite a bit more space - to the point that I wouldn't be able to fit both the audio and video for anything longer than about 1 hour, if I'm calculating it correctly. And I'm not quite sure how I could conver it to .AC3

you mean a wave file?

Not supported by DVD burning programs like DVDLab, Encore, TMPGencAuthor, etc.

Audio must be in either MP3 (not fully supported) or AC3.

What he should do:

If the original video is in avi format: strip audio with virtualdubmod as uncompressed PCM wave @ 16 bit 48000khz or if present AC3 encode it. Convert video to MPEG2 using whatever. Either mux them together yourself or let the burning app do it like DVDlab.

If original video is in MPEG format: Demux it and then convert the audio to either uncompressed PCM wave @ 16 bit 48000khz or directly to AC3 if encoder is present. Recode the video to MPEG2 and mux the sound and video together or let the burning app do it for you like DVDlab.

You may also make a menu too.

I like DVDlab pro myself.

EDIT: I use Canopus ProCoder 2 for MPEG2 conversion because it demuxes automatically and converts the audio to 16bit 48000khz PCM wave file. I then convert the audio to AC3 and let DVDlab pro do the rest.

Also, some DVD players require that set it as PCM in its own menu (usually requires that you take any discs out and press "menu"

Alright, I got it: dmux the audio, convert to AC3 (used Besweet from doom9.org), run video & audio through authoring program, and burn to DVD. Only potential problem I see is that on videohelp.com, where I read about doing this, they said that besweet doesn't produce a fully standard-compliant AC3 track, so it may or may not be compatible with whatever you try to play it in. Seems to work in my DVD player though

True, it usually works though.

Of course the alternative is to purchase the proper AC3 encoder and that is not cheap. You may be able to find a plugin or another app that has the legal AC3 encoder.

I think for now I'll stick with the freebie . Only other thing left to do, really, is fiddle with the color settings in WinTV - the DVD I just made looks great, except that it seems awful dark in some places, and overexposed in others.
