I'm very happy with the simplicity of DVD creation using TMPGEnc DVD Author. I especially like the menu creation system, where you pick the chapter points visually, and it builds the visual menus for you (In fact, I prefer 'my' menus to the fancy menus used on commercial DVDs - the commercial ones look good, but when all you want to do is watch a movie, having to play through all the intros and navigate the menus is a chore).

However, I have one project where I want to have two audio channels, and of course TDA does not support that. So a friend let me use his machine which had DVD Maestro, which supports multiple audio streams. To my dismay, however, creating menus in Maestro is MUCH harder (though I do appreciate, it's much more powerful). So I built a great, working DVD with multiple audio, but no menus (which actually has some appeal - pop in DVD and ... watch the movie ... radical concept!).

I also created a DVD using the same material using TDA, and built a nice simple menu (but of course only one audio channel). So ... since the source materials were the same (same m2v files), I'm guessing that the 'entry points' into the VOBs should be the same. So is there a way to 'merge' the menu system produced by TDA with the movie files (main VOBs) produced by Maestro?

I tried already taking the Video_ts.ifo/vob and vts_01_0.ifo/vob files from the TDA output and overwriting the same files in the Maestro output. This 'sorta' worked ... the menus came up on initial load of DVD, and selecting a menu item did launch into the movie at the (at least approximate) right place, but then the video froze after a second or so. So I think I'm 'almost' there ...

I've read quite a bit about IFO edit, and the various similar tools. My guess is, I need to run some tool(s) that will 'clean up' my ifo's and make them consistent. There are so many tools, I'm just not sure which one to start looking at first. If this is a fundamentally difficult process, I can simply give up; I won't need to do this often so spending days and days figuring it out is not worth it. Assuming it is fairly straight forward, I'm assuming the one gotcha with my specific plan here is that the Maestro output has two audio channels, but the TDA output has only one. I don't want or need a visual menu selection for second audio; I'm happy to use the remote's button to do that. But I'm guessing that even to use the remote's button, I have to have some entry in the IFO to support it.

Thanks for any guidance!
