I am hoping myDVDEdit will help me to solve this problem. I would be glad to make a paypal donation if it will work for me.

DVD authored in DVD Studio Pro.
Played back on WinDVD vers 8 and 10.
Pressing stop during playback, stops (correctly) but pressing play returns the disc to VTS_01_1 which is not what we want. We would prefer it launch to the root or resume.
Maybe this is something with WinDVD that is flawed, but cannot find a work around.
It appears WinDVD is treating Stop as if it were a Stop Stop.
Let me know if you have any ideas to solve the problem.

Many thanks.

Stop is not a DVD functionality, but a player functionality.
What I means is, when you press stop, the DVD playback stops without any interaction between the player and the DVD. Just like you switch off you TV.
If you press start, your DVD returns to VTS 1 because your DVD player has memorized the last position, not because the DVD asks for it.
Just like some televisions go back to the last channel you are watching, and others always reset to channel 1.

Look at the configuration menu of your DVD player, maybe it has an option to disable this functionality.

Ok, thanks for that.
Agreed stop ends the action of the DVD.
This is the part that is still illusive.
I just tested another DVD title using the Win DVD player (which is what my customer is using)
and pressed stop and play on my DVD's and it stops then plays VTS_01_01
I put in a studio disc with an animated video menu and pressed stop and play and it went to the animated menu. I checked the disk and VTS_01_01 is the FBI warning and VTS_02 is the menu. There must be something telling the player to go to the specific point on the DVD.
I was not on the animated menu when I pressed stop, but was on the FBI warning.
Seems Win DVD doesnt remember anything after stop, which is fine, but why does it go to VTS1 on some discs and VTS2 on others? That is the part of the authoring that I cannot find any references for. Jerome, help me solve this one and I will send you a nice donation!
Apple support wants $100 and I cant be sure they could even figure it out.
It may be too late to solve it for this one as the disc is planned to go to press today, and they client has agreed to move on since this only occurs with WinDVD.

Thanks!

To answer that, we should know what WiniDVD does when you press play after a stop.

One supposition is that it run Title 1 directly.
If this is really what it does, a good solution is to set a register to 1 in FirstPlay, then test this register in title1 and call FirstPlay if the value of the register is not 1

at the beginning of FirstPlay, insert
Code:
R7 = 1


in the beginning of VTS 1 - Pgc 1 - pre cmds, insert
Code:
R0 = 0x0001
if(R7 != R0) Call First Play


if R7 is already used in the rest of the DVD, choose an other register.

you could add this test to all yours titles if you think it could be necessary.

I hope that's help you.
