I had problems with ifoedit saying that last sector was not corresponding to file size of a VIDEO_TS.IFO file.

So finally after lotst of desperate uses of other programs I tried DVD-RB WITHOUT compression.

And indeed, the IFOEDIT-error was gone, BUT:

When using IFOEDIT I noticed that RB-PRO changed the material to NTSC in the primary VMG section of the VIDEO_TS.IFO !!!!!

It even makes general VMG attributes saing it's MPEG 1 !!!!

What's this ????

IT's also setting options diffent in main VMG description such as LETTERBOXED etc...

I don't know if it's destructive for youre DVD playback, but SURE this has to be not the case. The original VMG properties that were PAL should be kept !!!

Not overwriiten by DVD-RB with NTSC settings !!

JDOBB ?

Please explain to me....

DVD Rebuilder CERTAINLY DOES NOT change those values. Something else is involved and it's probably your use of IFOEdit. Is this the same DVD you were modifying on in this thread?

So can I assume you changed it with IFOEDIT, made some mistakes, and have now decided you couldn't possibly be at fault so DVD-RB must have done it?

Are you going back to your old offensive ways, apfraats?

Get your facts straight before posting this rubbish.

Watch out before reacting like that JDOBBS !

I've tested it correctly and WILL DO IT AGAIN.

DVD-RB makes the changes in the VMG attrubutes at the main level of the
VIDEO_TS.IFO !

I'm sure about that.

I even compared the VIDEO_TS.IFO of the DVD_RB source directory to that of the DVD-RB output directory, and sure it's changed.

Yes it's the same DVD.

The fact that it's probably not noticed by anobody it that at VTS_XX.IFO level the info is correct BUT NOT at VMG attributes level at the VIDEO_TS.IFO file that DVD-RB probaly rebuilds, because the Ifoedit error concerning last sector of IFO file was gone !!!

So DVD-RB rebuilds/changes the VIDEO_TS.IFO file.

I ran it with the 'NO COMPRESSION' option.

If you don't believe me and saying I'm offensive to you, youre completely mistaken here !!

So behave and take it seriously !

I WILL TRY AGAIN.
I WILL TEST AGAIN

All tomorrow.

I didn't even touch the particular line with IFOedit and did no editing in HEX or something like that at all !

I WILL POST THE VIDEO_TS.IFO of the source and that of the output of DVD-RB !

You can see for yourself.

Probably again it's not making DVD's really NTSC beacuse again at the VTS.IFO level the attributes are OK !

But it's just not compliant and VIDEO_TS.IFO attributes should be the same as the correspondenting VTS.IFO attributes..........

So just hold youre horses.

DVD Rebuilder doesn't change any of those attributes. They stay untouched from the original. The only exception to that rule would be on a Movie-Only DVD, and that is because the IFO is created from scratch.

I just tested it again.

I thought I was sure.

But now these VMG attributes are the same before and after processing with DBD-RB....????!!!!

What the hell I did wrong, I don't now.
I don't even have any NTSC dvd's..........


But YES YES YES, I'm sorry.

We all make mistakes....... :stupid:

I just was to quick about this.

I'm sure I've read NTSC but for now it's impossible to reproduce.....

So youre right sorry.

I think I go and see my Shrink tommorow. Probably having hallucinations...

Don't worry about it... it happens.

I probably opened a wrong VIDEO_TS.IFO

You have to watch out using Ifoedit, cause all previously opened files are in memory, and you have to be sure where the focus is.

Now I've opened several PAL-DVD's and on more than one ocassion an IFO is reading:

Menu attributes:
Video: MPEG-1 720*480 (NTSC) (NTSC 525/60) (4:3) (pan scan & letterboxed)

That is really stupid to see on PAL-dvd's. But it happens more often.....

Probably these menu-attributes are not used and original authoring was NTSC, later on converted an re-authored to PAL.

So I have had probably focus on a wrong VIDEO_TS.IFO

Again, sorry.

By the way, can you explain these NTSC attributes on a PAL DVD ?
And surely MPGEG-1 looks someway stupid to me too.

Remember that some DVD houses (whether authoring tools or individuals) make poorly mastered discs. As he and others have discovered, you can see 4:3 being specified for 16:9 material, vice versa and so forth. Or progressive material being flagged as interlaced and vice versa, etc. 4:3 gets you full screen, but on an actual wide screen video stream sans black bars, the video output would be distorted (unless, and I don't even know then since I don't own one --- a person used a widescreen TV?) Some attributes are ignored on some menus, some on different parts of the structure are not. While I lack the insight that JDobbs has, it's clear that this happens (in the sense of improperly mastered material).

Yep,. indeed, I think it's just a fact that DVD's are sometimes poorly mastered. Although one should expect commercail DVD's in which case you have to pay big bucks for, are correctly mastered.


But with the DVD in my case, there was a wrong 4:3 setting leading to wrong restults on 4:3 TV. It didn't give the upper and lower black portions, but it gave the whole picture in 4:3 Anamorphic, so totally disorted !. Lukkely the TV has a 16:9 setting in which it compressed the picture vertically and then it looks nice. But if you haven't seach a 'feature' on youre TV , you are in bad luck. So I did what DJOBBS recommended me and flagged all as 16:9 Letterboxed with IFOedit,. and it was ok.

You have to watch out, because of the fact, you see all the atrrributes in VIDEO_TS.IFO but also in VTS_XX_.IFO !!

I have even seen that in the VTS_XX.IFO the correct attributes were used but NOT in the VIDEO_TS.IFO. Probably is player is more interested in the information of the VTS_XX.IFO, so this should be correct. The same information in VIDEO_TS.IFO is disregarded as far as I know.

Nevertheless they should be the same.

Now if 'weird' things happen, I take Ifoedit and correctly flag all IFO's.

You have to watch out because some menu's are really 4:3 and some material can be really 4:3 for example in the Extras....

If you own a widescreen TV, you have to set WIDESCREEN modus manually. So the flagging of the material hasn't much infuence. Only Mixing 4:3 and 16:9 material on a DVD is very annoying because you have to switch manually between settings of youre widescreen TV (this is True for my Philips Pixel plus 81 cm anyway).

Theoratically it should be possible to have the TV switch automatically because on SCART plugs used here in Europe there is a special sensing PIN on which the player can set a DC signal, signalling 4:3 letterboxed, 4:3 Pan scan or 16:9. But in practise I never seen this be used.....
