Two Different Audio Streams In The same VTS.

[GangstaRap]

Hi guys!
I was just compiling authored DVD with DVD Lab Pro, and it warned me
that since i have to audio streams (MP2 and AC3) at the same VTS, it might wont work at the DVD player.
trying to encode the MP2 to AC3 caused me big headache (out of sync), so its not an option.

how critical is this really?
is this something to be worried about?

Thanks in advanced!

Edit 2:

i figured it out.
i managed to fix the out of sync output,
but i'm still interested though...
if anyone knows...

If you see blue glasses, than in 99% of the time DVD is fine.
AC3 is preferred audio, but MP2 is also standard. If you have two audio tracks for one movie in same VTS, it should be no problem.
You can compile DVD and burn it to RW disc to try, but I do not think there should be a problem.

Only problem will be, if you have two "Movies" in one VTS and each has different audio track as track1. Than two VTS is needed for proper playback

I think it's over cautious. Just try it and see.

Hi guys!
thanks for posting.

i dont care "losing" a DVD-R.
actually, i did try it on my Pioneer device and it worked fine.
the thing is that the DVD i'm authoring is a birthday present to my nephew,
i dont know which DVD player he's gonna play it,
and i wanted to make sure he would be able to play it no matter which DVD player he has.

thats was exactly the case.
it was two different movies - each one had two different audio stream compression (AC3, MP2).

it also keeps warning me whenever i add a video with an open GOP to my project and i've never had any problems playing it on my DVD player.

Unfortunately, your goal is impossible. Even if you use the very best media, burned correctly and you adhere to all the standards in making DVDs, there's no way to guarantee that someone won't buy some piece of crap DVD player that won't play the disc anyway through some defect in the player itself. Some people have DVD players that can't even play some professionally pressed DVDs. I'm sure this would not apply to your nephew, but finally you can't discount the idiot factor where someone who knows nothing will do something like try to play the disc with the label side down.

The odds are that your DVD will be OK, but again, if he has some piece of crap player, maybe it won't like your brand of disc or it won't like that you used DVD-R instead of DVD+R (or used DVD+R instead of DVD-R) or some such nonsense that you can't even predict. It's unlikely but I guess there is always the possibility that somebody might make a DVD player that will refuse to play the disc because the audio isn't the same format in both movies in the VTS. If you have a lot of time on your hands you could convert the MP2 audio to AC3 with something like BeSweet GUI and then remake the DVD. Both movies in the VTS will have AC3 audio and you'll get no warning. The odds of your nephew's DVD player not playing the disc correctly because of MP2 and AC3 audio is probably 1 in 1000 or less. There's a much higher chance his player will simply not like your media. I'd suggest that you just give it to him as is and hope for the best as the odds are high that it will be OK. Remake it with AC3 only if there are problems. There's just no way to give you a 100% guarantee it will work no matter what you do. If your nephew's DVD player was bought within the past year or two, the odds are quite good that it will work. Older players will be much fussier about what they will play.

In the USA, "the very best media" means Taiyo Yuden and Verbatim. Sony can be good or bad depending on who made it and where and you have to know what you're getting if you buy Sony. Everybody else who sells media in the USA basically sells junk. If you used another brand, it may or may not work, depending the age and fussiness of his DVD player. You could also try burning to Taiyo Yuden or Verbatim discs for best results. By the way, Pioneer makes very good DVD players and they are very tolerant of DVDs that aren't quite 100% according to spec and were made with lower quality media.

This is DVD standard. One VTS has to have frame size and audio same. That is, you cannot mix 16:9 and 4:3 in one VTS, same goes for audio.
You are lucky that it play without player locking up.
Open GOP is not a problem.
But like jman say, burned DVD is newer 100% compatible with all players. It is good practice to start with reliable media.

Thats what i did,
also - used Silver Line media.
hopefully everything will be alright.
