Same DVD, different playback...

[setarip_old]

(Moved to this sub-forum because the answer undoubtedly lies somewher in the .IFO navigation code)

I just came across an anomalous situation regarding different standalone DVD players apparently interpreting the same DVD coding differently.

Before considering purchasing the "New" release of "Lady and the Tramp" (Region 1), I thought I'd see if the grandkids might be just as pleased watching the earlier, initial DVD release - which I had backed up a couple of years ago.

At that time, I also had several different standalone DVD players than I now have - and they all played this backup flawlessly.

Simply stated, currently, my SONY DVP-NS725P plays the backup flawlessly. However, both my Philips DVP 642/37 and my cheapo GE1101P display FALSE camera angle icons during both the first and final chapters of the movie.

I was under the impression that ALL players with the "DVD" logo MUST interpret all DVD navigation code in exactly the same way.

If anyone has an explanation for this unusual dichotomy, I'd really appreciate hearing from you ;>}

By the way, my original, purchased DVD plays flawlessly on ALL THREE players!


**EDIT** The structure of the DVD does, in fact, include the option in the "Setup" menu to select from amongst three spoken languages (English, French, and Spanish). The language choice made also controls the written language of the opening and closing credits. This is apparently what is triggering the appearance of the FALSE camera angle icons that appear when loading the burned DVD into only two of three standalone DVD players...

What software program did you use to edit this DVD with?

[setarip_old]

I used only DVD Decrypter to rip all files in "File" mode (No compression was required) - but I don't see how that would be relevant to my question, as to why, when playing the burned DVD, two of three standalone players show a false multiangle option icon (It is not selectable once you've made a language selection from the menu), while the third player doesn't - and all three play the original without showing this false multiangle option icon...

Thanks for asking though ;>}

Most of the time this is from bad authoring. That's the reason I ask what program you may have used, but since you did not need to edit do to the size of the DVD files being small enough to fit on a DVD5 then the problem was in the original authoring. One probably could find it by spending a little time using a editing program.
All players do not excute in the same way by reading every command. That's the reason when you edit IFO's and change the commands, so players will play your backup fine and some wont. Do to the way we rip, edit, burn and the media we use, it is not a 100% guarantee that every backup we do will work on all DVD standalones regardless if it is playback or causing a false camera angle to display. I had an old GE 1101P that some poorly authored originals DVD's would cause certain icons to come on when the disk did not even have that option.
The DVD-Rom media and the way they are pressed (burned), meet the required standards to play on all DVD players most all the time.

All players do not excute in the same way by reading every command.As I understand (as I stated in my initial post), if a player has the DVD logo MUST interpret all DVD navigation code in exactly the same way.

Also, this would not explain why a 1:1 rip would generate the false angle icon on 2 of 3 players and the original, purchased DVD doesn't generate a false angle icon on any of those same players...

That's caused by a well known problem.
When ripping, you have probably used the DVDD option to remove the PUOs from the IFOs and VOBs. IMO, it's not a good idea. Let's explain.

When there are several angles in a title, and the player is playing a multi-angle cell, it is theoretically possible to change the angle with the remote, unless a PUO prohibits this function. The angle icon displayed by some players is there to inform the user that it is possible to use the remote to select another angle. Of course, this angle icon should not be displayed if the original Angle PUO is still there.
The Sony players are smart enough to avoid displaying this stupid angle icon. That doesn't mean that the players are interpreting the DVD differently. It's only an onscreen display, and nothing else.
IMO, a player should have at least a setup option to turn off this angle icon "feature" (or call it "bug" if you prefer!) It's an important criterion when you buy a standalone player.

If you want to remove this angle icon display, select the multi-angle display in PgcEdit, and tick the Angle Change PUO. Save. Should work.

Also, when ripping, you should untick the remove PUOs in IFOs option in DVDD, and remove them selectively with PgcEdit. (I prefer to remove them from the VOBs anyway, since it's difficult to remove them manually.)

BTW, it's one reason to avoid using DVDFab Decrypter: you cannot keep the original PUOs with this ripper. With DVDD, it's an option.
Also, note that there is a function to import back the original IFO PUOs in the PUO plugin for PgcEdit. You can use it to avoid the DVDFab Decrypter limitation.

Also DVDD default settings are set to non removal of IFO/VOB PUOs unless you have been mucking with settings.

@r0lZ

Thanks for the explanation!

1) I would NEVER use DVDFab Decrypter (Both because of the way it operates and personal reasons relating to the publisher)

2) I've always used DVD Decrypter set to "Remove .IFO PUOs" - and this problem was resolved by unticking this.

3) Since this was the focal point of my question, I hope you won't mind if I press you for further explanation. I'm at a loss to understand how your statement isn't a contradiction within itself: The Sony players are smart enough to avoid displaying this stupid angle icon. That doesn't mean that the players are interpreting the DVD differently. It's only an onscreen display, and nothing else.How can differing displays NOT be the result of differing interpretation of the DVD? Something in each of my different players is triggering the appearance or lack of appearance of the camera angle icon. If it's not being triggered by information on the DVD, what is the source?

4) I never remove VOB PUOs, for the very reason that in the past, I've seen doing so result in this false angle icon ("The Incredibles" is one that comes to mind) - but before this "Lady and the Tramp" old version, I've never had the removal of .IFO PUOs cause this or any other anomaly.

Both players interpret the IFO/VOB correctly: there's several angles available to the user at this point of the playback and there are no puo preventing you from switching angles. In such cases some players choose to show an "angle icon" on the TV while others don't. In all players, though, you could switch angles by pressing the angle button of your remote. My player always shows the angle icon and I can't disable it. I don't see any self-contradition in r0lZ' explanation...

p.s. the appearance/not-appearance of the angle icon is NOT part of the DVD specs. Maybe that's the source of your confusion.

[setarip_old]

@jeanlthe appearance/not-appearance of the angle icon is NOT part of the DVD specs.If that is correct then it is part of the answer to my original question!

Thanks ;>}

[r0lZ]

I couldn't have explained better, jeanl! ;)
The angle icon has no more importance than labelling the Title Menu button on the remote "Main menu" or "Up menu", or even anything else. In each case, the function it does is the same.

[setarip_old]

Thanks to all for the input!

Most importantly, the grandkids thoroughly enjoyed viewing - and didn't have a clue that the DVD was older than some of them ;>}
