More LPCM problems

Jdobbs this morning I did Pink Floyd The wall also with LPCM tracks.
The VIDEO_TS come out at 4,79 gig with DVD RB 0.40 rejig.
With the LPCM unchecked but when tested with powerDVD the track was still present.

Here is some info.
Checked LPCM tracks :

- Reduction Level for DVD-5: 37,8%
- Overall Bitrate : 1.601Kbs
- HIGH/LOW Cell Bitrates: 2.121/72 Kbs

Unchecked LPCM tracks :

- Reduction Level for DVD-5: 37,8%
- Overall Bitrate : 1.601Kbs
- HIGH/LOW Cell Bitrates: 2.121/72 Kbs

Exactly the same bitrate.

Ifoedit VTS_01

Title Set (Movie) attributes:
Video: MPEG-2 720x576 (PAL) (PAL 625/50) (16:9) (letterboxed)
Audio 1: English (Dolby AC-3) 6ch 48Kbps DRC (ID: 0x80)
Audio 2: English (Linear PCM) 2ch 48Kbps 20bps (ID: 0xa1)


Ifoedit VTS_04

Title Set (Movie) attributes:
Video: MPEG-2 720x576 (PAL) (PAL 625/50) (16:9) (letterboxed)
Audio 1: English (Dolby AC-3) 6ch 48Kbps DRC (ID: 0x80)
Audio 2: English (Linear PCM) 2ch 48Kbps 16bps (ID: 0xa1)
Audio 3: English (Dolby AC-3) 2ch 48Kbps DRC (ID: 0x82)

vobedit VTS_01

VTS_01_0.VOB no audio streams present
VTS_01_1.VOB LPCM 0xa1,AC3 0x80

vobedit VTS_04

VTS_04_0.VOB AC3 0x80
VTS_04_1.VOB ~ VTS_04_5.VOB
AC3 6ch 0x80,LPCM 0xa1,AC3 2ch 0x82

I hope you can do something with it.

A temporary way to resolve this issue could be to reauthor the DVD with dvd-shrink, removing the LCPM track and setting the video compression to "no compression". Then you compress the dvd reauthored with DVD-RB.

Yes that's the solution.

First DVD shrink then tried again with dvd-rb 41 and rejig ,the video_ts come out at 4,27 gig.

Thanks!

Did you use DVD-Shrink to remove the LPCM track?

Yes I've used DVDShrink to remove audio and sub tracks aswell (with no compression) and then feed that to dvd-rb and it works great. No need to reauthor if youre just removing tracks.

Well, usually I do strip down what I want in dvdshrink. Just thought I'd try letting Rebuilder do it this time. Unlucky coincidence.

The frustrating part is that you shouldn't have to use Shrink first. DVD-RB should do it right... but I can't for the life of me figure out why it isn't. Well I guess this is where I get in my car an go buy one of those LPCM DVDs... man a guy can go broke writing DVD software!!

I removed the LPCM track with dvdhsrink and now it says 61% reduction/avg bitrate of 2,400. It was 41%/avg 1,800 before.

jd, yeah, it [upsets] me off to think of you spending money buying dvds so you can write free software. Maybe try doing what dvd2svcd did: Make an Amazon wishlist.

You personal info is kept private, yet it is very easy for somebody to send you a problem dvd. I kinda feel like if somebody wants something fixed they can at least chump up an example disk
