Newbie Needs a li'l help on DVD Audio

[dinhphan]

I have Two Music DVDs. Using DVDShrink I saw the first one has the audio format 1. AC3-2ch 2. AC3 5.1ch, the second one has 1. LPCM-2ch 2..AC3-2ch. AFter copy and paste certain chapters on each DVD with DVDShrink and combined them into one single Title Set Using VOBEdit and IFOEdit, I then burned this to a DVD. When I play it in my topset DVD, All the chapters in the first DVD will play with sound AC3 5.1 but no sound at all on the chapters of the second DVD and I can guess why but don't know how to go about with the business of MUX & DEMUX to fix it, Any advice would greatly appreciated.

PS. The DVD has Audio on all chapters when playing windows Player or Power DVD.

"When I play it in my topset DVD, All the chapters in the first DVD will play with sound AC3 5.1 but no sound at all on the chapters of the second DVD"

This is due to the fact that you've joined parts of two DVDs with disparate audiostream sequences (as well as format) into ONE TITLE.

Instead, join them as TWO TITLES on one DVD...

Thank you for your reply.

Yes, I thought of making into 2 separate TS's. But if I do that, then would I be able to navigate between th 2 TS's using the remote control ?

And here's what I also found after posting my question, I play the same DVD with another DVD Player and it works, so... it seems that with different DVD Players, some has the intelligence to switch to another audio mode.

My question is... Can I de-mutiplex the 2nd title set then convert the audio stream to be the same as the first TS ??? and if so, what software do I need ?

Thanks again.
