Help...which PGC do I choose??

[Superturtle]

I'm backing up Two Tower Special Edition. When DVDDecrypter loads up it shows me two PGC files...

PGC1 [01:46:31]

AND

PGC2 [01:46:31]


Which one do I choose and why are there two in the first place?

I haven't looked at that particular dvd but it probably contains both the widescreen and fullscreen versions.

Thanks for the reply sidewinder...I load Vob 1 file from both PGC rips and they both are of the widescreen format. I'm assuming full screen means 4:3 and widescreen is 16:9.

This might be a seamless branching dvd. Does it have the theatrical, Special, or Extended versions all on the same dvd?

Superturtle-Yes, that's correct. You're referring to the movies's "aspect ratio". One way to explain aspect ratio is to say that it means the ratio between the width of the picture and the height of the picture.

4:3 full frame/aspect ratio: Refers to a screen that is 4 units wide and 3 units wide (i.e., 1.33:1 aspect ratio). This is the aspect ratio of conventional analogue television screens, most computer monitors, and DVD's that are published in 4:3 aspect ratio.

16:9 widescreen/aspect ratio: Refers to a TV screen that has a 16:9 aspect ratio, or DVDs that are published in 16:9 aspect ratio.

hi,
i understand your confusion on this topic as i had pretty much the same problem when backing up LOTR FOTR SEE quite some time ago.
iirc those two PGCs were simply duplicates. or in other words, those two PGCs actually played exactly the same video - to the last CellID :)

so iirc you can either recreate the exact same structure with the big 3 and a bit of manual editing in scenarist, OR you can simply throw one PGC away, and keep the one you like.

It is possible that one of them jumps to another layer to display extras during the movie (ie how the special effects are done etc) then jumps back to where you were (this may be the seamless branching as described earlier, but I don't know about that)

You can tell (without watching it to see) by checking for layer breaks in IFOedit the one with the special features will have many layer breaks and the film on it's own will have one layer break.
The PGCs are the same length as the other material is simply referenced

Both PGC's contain the same video AFAIK, but one of them have the commentary audio/subtitles referenced and the other the regular audio/subtitles.

Which one do I choose...? Are you doing a movie only backup? Here's what I would do. Play your DVD in IfoEdit and check the Status window in DVD Play panel. It should display Title #. Open up VIDEO_TS.IFO and look in / VMG Overview / Number of Title Play Maps section. Look for your Title #. On that same line, your will find your Title Set number.

For example below, my Title resides in Title Set VTS_01. TTN means Titleset Title Number so TTN 1 is Title 1 in VTS_01.

VMG Overview

Number of Title Play Maps: 3 (VMG_PTT_SRPT)
Title 1: VTS_01_*, TTN_1 (Angles: 1) (Chapters: 19) (Start Sector 1185)
Title 2: VTS_02_*, TTN_1 (Angles: 1) (Chapters: 2) (Start Sector 1524375)
Title 3: VTS_03_*, TTN_1 (Angles: 1) (Chapters: 2) (Start Sector 1608135)

I would then open VTS_01_0.IFO and check which PGC is TTN 1 (Title1). Most likely it'll be PGC_1.

This is the PGC you need to rip.

The region 2 version has 11 program chains 5 or six of which are the full lenth film 1 hour 42 minutes 11 seconds (shorter due to the reduced frame rate)
Decrypter shows only 2 program chains though (as with yours)

Anyways title 1 is the film and all the soundtracks
