Oh where oh where did my audio go?

Source: .tivo file, DVD compliant
Trimmed beginning and end via VRD, saved video as MPG (DVD compliant).
Using EMC8, burned and played on DVD player, resulting with video but NO audio. I played the MPG file on the computer to make sure, and yes, it has audio.

Anyone have any ideas?

TIA,
Jeeves

What's EMC8, and how did you author your DVD?

CTRL-L with the source file opened in VideoReDo and post the results. Are there any logs still around from when you authored it?

I tried Ulead Movie Factory 4 with : Do not convert compliant MPEG... unchecked with the same result... Heck, I have to do another check because it may have been uLead MF 4 originally... UGH!

Please check Do not convert... in DMF. Things will go a lot quicker.

What version of DMF4 do you have? Standard, Disk Creator, SE, LE? It may or may not handle AC3 audio.

It's SE- I could have sworn that I did this successfully before... Maybe that was when I allowed it to reencode though. I make sure that the "Check for DVD compliancy" is NOT checked.

I would bet that your SE version does not handle AC3. If you check "Do not convert compliant..." sometimes DMF can pass through AC3 audio and have it author correctly.

Your other option with DMF would be to convert the audio to MPEG in VRD using the Options button in the file save dialog box.

If Pat is correct and it is that DMF cannot handle the AC3 audio, you could also look at another program for authoring the DVD. There are several free utilities available.

I think what Pat was saying is that AC3 audio support in DMF will depend on the version / license you have - there are clearly versions that will support it.

Indeed - but the thread really is about a "Why?" to do with the OPs authoring. App advocacy may be relevant if the OP really wants to, or has opportuinity to switch apps, but he / she may just want to know why, and if there are any ways around it, rather than having to get into a different learning curve.

The "SE" versions of DMF depend on the OEM supplier and what features they were willing to pay Ulead for.

Here is an informal list that I know of, but don't quote me.

DMF5 full versions
DMF4 full versions
DMF3 Disk Creator (not standard)
DMF2 LE (came with MediaStudio Pro)

These versions supported encoding to Dolby and would pass through AC3 without reencoding.

Audio Problem solved (DOH!)

This immediately identified that the problem was in the Tivo itself, or an audio connection problem between it and the source (a satellite receiver). I connected the satellite receiver directly to the TV and heard both channels. I reconnected the TV to the Tivo and replace the audio cable between the satellite receiver and the Tivo.


Sometimes the basics are simply overlooked.

Problem solved.
Thanks
