Read the help file, the're very informative. When you dragged the video file to the Movie window, did you also drag the audio file there too?

[dcsos]

Also the AUDIO_TS folder on a DVD Video is always an empty folder*

The VIDEO_TS folder contains both AUDIO AND VIDEO in a -new to dvd -format called .VOB

Do what RACER says,
as you should have seperate VIDEO and AUDI assets to be imported..

Maybe you need to DEMUX (seperate the Audio from the Video) using TMPGENC

or buy another AUTHORING application like DVD ARCHITECT that will accept already MUXED files!

*DVD AUDIO titles put .AOB's in this folder

[RCAMPBELL]

i have read the help file

and i did also drag the audio to the movie section

still cant figure this out

[dcsos]

Maybe the Volume is down:-)

or post some details and we could try to help you
Where did you get the MPG files what kind of audio do they have in the steam and such..
POST AWAY

I am having a similar problem ... authored some mpeg1 files with TMPGnc Author, burned with Nero. There is nothing in the Video folder (which I understand can be OK) but I can play the DVD on my computer with sound. When I try it on my standalone, I get video only. Hardware seems OK, I can play vcd, svcd and commercial DVDs on my RCA standalone.

Hope someone has an answer

Your stand alone RCA cannot play the kind of AUDIO embedded in the
MPEG stream used for home authoring.

Apparently the makers of that box decided all you would watch was HOLLYWOOD fare with .AC3 format sound embedded in the MPEG.

The solution is to use a different AUTHORING program that will make .AC3
on your DVD's like a hollywood title-(SONIC FOUNDRY's ARCHITECT)

for VIDEO CD's or SVCD's your stuck with a lemon
as the VCD and SVCD specs will not allow this kind of sound file.

ALSO you say the VIDEO_TS folder is empty...
NOT POSSIBLE unless you are talking about a DVD AUDIO only title

If youre talking about a VCD there is no VIDEO_TS folder instead you have an architecture than is composed of
FOUR folders with differing contents
The actual material resides in the MPEG or AV folders on these kinda discs

Well RCA is a French product now, maybe they're getting back at us.

The thing does play everything else ... VCD, SVCD, CD, & commercial DVDs.

I meant AUDIO_TC, not VIDEO_TC was empty, sorry.

I'll look at Sonic Foundry ... hope the have a trial version

Thanks

Problem: Can’t hear audio from DVD player. I finally figured out what was happening.

This now seems pretty basic, but there was a pretty big learning curve for me, and I suspect others. My guess is this is a generic problem with a number of products. It took me awhile to understand what was happening, and this may save someone else some time.

This RCA player (and many others) handles CD, VCD & SVCD video & audio as mpeg, and plays just fine.

The DVD outputs are separated for video (mpeg2, Svideo or component) & audio (pcm, coax or fiber optic) for input to a surround sound amp.

My Pinnacle Studio 8.5 DVD authoring software creates mpeg2 video and LPCM audio, which will play just fine.

I always archived my movies by saving them as mpeg files and storing them on CDs. Studio 8 (and maybe others) saves both video and audio as MPEG (seems logical now). There is no option to save the audio as PCM (even tho there is a pull down tab for audio format). The problem comes when you later re-burn or re-author.

During playback after re-authoring 3 tracks with TMPGEnc author and burning with Nero, the standalone player has no pcm audio data to send to the Amp, even tho the audio is there (as mpeg1) and will play fine on the PC, and in fact actually outputs the audio to the stereo jacks (if they were switched on)

Studio 8 does save a DVD disk image which can be archived for later re-burning, but flexibility to easily combine different clips is lost. You can combine different projects with cut and paste but you have to somehow archive the project (which resides in different folders) and then re-render as a new project. In my case over 4 hours for a 55min show. If the mpeg2 file had pcm audio, It would have taken just a few minutes to combine the 3 clips. Assuming I knew enough to save it that way!

Luckily my ultimate backups were digital tapes for the 3 clips, so I was able to recapture and finally recover, but it was a long process.

I just wanted to second the post saying you aren't using AC3 audio. Indeed, lots of authoring packages don't use AC3. This isn't that big a deal, however. Just run RCA cables in addition to your regular cables (optical, coax, etc). Then your newly authored DVDs will use the RCA cables for sound.

Once you get comfortable with that, you might want to upgrade to authoring software that will accept AC3.

[ayed]

Thanks, you're right about adding the RCA cables (even tho the directions say either or).

Do you know any moderate cost authoring/editing packages that use AC3 ?

[bek]

Hmm... sorry, I've got a list at home somewhere, but don't know offhand.

Most ULead stuff DOES NOT use AC3, except for the special DVD Workshop AC3 version. ULead is what I'm most familiar with.

I believe DVDit! might be AC3, but I've had bad luck getting mine to work well.

You can convert your current audio to either ac3 or PCM (either is supported by the DVD standard). For AC3 try either BeSweet GUI or headac3he:

Most people seem to like headac3he better. More than likely your DVD player does not support playing DVDs with MP2 audio streams (if it plays VCD/SVCD you have to ask why, but who knows). If that's the case the fact that you can author in other programs which do accept mp2 audio streams will not fix your problem.

Don't forget to re-sample to audio to 48khz (if necessary).
