DVDR: No sound on SOME dvd players but works fine on others

[bek]

A friend of mine made me a DVDR that works fine on my old Toshiba SD-1600 in the bedroom. It also works perfect on my PC.

When I try to play it in my SD-4800 that has a receiver with surround sound, there is no audio.

My surround sound is in fine working order (I tested it after this). There is something unique about the DVDR. My friend used TMPGEnc to encode the disc a DivX AVI he downloaded.

Any help would be appreciated! I am desperate!

Thanks,
Brian

Either the DVD player doesn't fully support DVDR or more likely it doesn't support the audio bitrate that it was recorded in.

[ghoster]

best guess would be the audio wasn't converted to 48 kps.

the audio is probably PCM format, convert it to 48khz 5.1, and u should be ok. use besweet with ac3machine from doom9 site.

Could be he used MPA for the audio instead of a PCM WAV or an AC3 file. Your other player possibly can not read MPA audio or your surround sound system can not.

I have a copy of my friend's TMPGEnc template! It appears the sampling frequency is 48000Hz and bitrate is 384. Is there a way I could include the template for you guys to see?

TMPGenc huh? That's most likely the probelm. TMPGenc produces MP2 audio tracks, which while they will work on 95%+ of DVD players, are not DVD standard. Only PCM and AC3 are actually supported.

Can I switch TMPGEnc to PCM or AC3?

[G-man]

Many DVD players have menu settings to play the Mpeg audio (which is what TMPGEnc creates) instead of using the PCM stream. Play around with your player's audio settings and there is a good chance you will get it to work. But I think you will probably need to have the RCA left/right audio jacks connected between the DVD player and your receiver as well.

Can I have the RCA cables and my S-video connected at the same time? I'd hate to keep swapping them back and forth.

Thanks for all the info--I will experiment with it tomorrow evening (getting too late now).

[G-man]

Both your RCA red/white audio (not the yellow if you already have S-video) and your optical/coax 5.1 audio connection at the same time is what you want.

Actually MP2 audio support is mandatory for DVD players sold in PAL regions, it is not required for DVD players sold in NTSC regions. The only format that is required by ALL DVD players is PCM.

Having said all that, it is most likley an issue with audio formats.

Bek, you say it doesn't work through the surround sound receiver. Have you tried audio out (stereo) direct to the TV. This would tell you wether the DVD player is handling the mp2 audio or not. If it works in this mode, you may need to change a setting on your DVD player or receiver to get it to work. I seem to remember on my Panasonic DVD player there was a setting for the optical out that allowed mp2 audio to be output as is ( for mp2 decoders) or converted to PCM (for the more common dolby pro-logic/Ac3 receivers).

Hope this helps.

Didn't I just say that
