Demultiplex....Re Author....

[phantomengineer]

My first problem is which forum to post, it cover several. The issue is I have a DVD R with AC3 audio encoded with BeSweet that won't play on my Pioneer DVD player. So I demultiplexed with VobEdit, then re encoded the audio from AC3>WAV, then WAV to MP3 with Ac3Tool. Then multiplexed with TMPGenc. That took up a bunch of yesterday. Today I tried to author the new file with DVD Lab. When I try to compile it tells me it's the wrong MPEG audio format. But wait, it gets better. I tried to save the project to come back to it later but DVD Lab won't let me "Save As". It just won't do it. I clicked "Save" and it saved it as dvdoproject that my computer can't open. IT SAVED IT IN A FORMAT MY COMPUTER CAN'T OPEN. What good is that? Now all the work I did today on DVD Lab is lost. I just want to re author a DVD so I can ply it. Why is everything to do with digital video so convoluted and difficult? OK that last part was just a rant but I think justified.

The real problem is why your DVD with AC3 audio doesn't play on your standalone DVD player.

If you really want to change audio format, you have to encode to mp2 (mpeg1 layer2), NOT mp3 (mpeg1 layer3) which is not part of DVD standard.
Be aware that not all standalone players can read mp2 audio.

bsweet can re-encode from ac3 to mp2 in one pass, no need to work with a wav file.

Thanks Milo, but I expected the BeSweet encoded disc not to work, I just thought it would be easier to fix. I think it's quite an oversight for BeSeet to have such a bug. Pioneer is a fairly large DVD manufacturer. But it still dosn't address the DVD Lab issue. Why doesn't it save the project in a unuseable format? and if MP3 is not a DVD compliant format why does Ac3>WAV use it? There was no option for MP2. And I have to repeat, why is everything to do with digital video so convoluted and difficult? Just wondering.
