DVDRB Pro and removing audio tracks

[valnar]

I have a minor issue with DVD Rebuilder Pro for awhile now and wondered if JDobbs could fix it. I've been a beta tester since it came out.

Every movie I backup with DVD-RB, I end up running it through DVD Shrink with no compression to clear the Audio tracks that I removed previously with DVD-RB. When I remove unwanted audio with DVD-RB, my software DVD players still show the tracks exist, although with no sound (data). When I filter it through DVD Shrink one last time before burning the image, I unselect those same audio tracks and DVD Shrink removes them completely. In a software DVD player like PowerDVD, they are no longer selectable. It's a little cleaner, especially when you use a button to just toggle through audio tracks when watching a movie.

Sorry that I don't know the exact DVD format parameters to describe what I mean, but it's easy to replicate. Could this function be added to DVD Rebuilder Pro?

its there. just use the audio track remapping function

[valnar]

Ah.. thanks. I'll read up on that. I never ventured out of the basics.

Does it work the same?

you can correct the stripped streams with Ifoedit too

i learned it with this great guide from 2Cool

I checked the Audio remap function and it's not quite the same. I don't want to remap, I want to eliminate.

Feature request?

Before DVD Rebuilder was around I used to use Recode to back up movies and it used to do the same thing - it would remove the existence of removed tracks when changing between them. I always wished DVD Rebuilder had that feature as well rather than just choosing an audio track with no sound on it.

I still remove unwanted audio tracks with DVD Shrink if it won't fit on a single disc, but I run it through DVD Shrink before and save it uncompressed, I then run it through DVD-RB

I also use DVD Shrink to strip any annoying stuff from the start or end to give DVD-RB that little bit extra to play with. Mainly the rubbish that the companies put at the front like their logo, it might only be a few seconds, but then again I've seen it over a minute. It all help simprove the final bitrate

Sometimes they sneakily add it at the very end of the titles as well. Like we all watch movies until the very end of the titles

Hmmm... I'll look at it again, but if I remember correctly there are some landmines involved when you do that. Menus can reference audio tracks that don't exist -- and I really don't want to get DVD-RB into menu editing (except reencoding).

There is a function in pgcedit where you can disable audio tracks that have been stripped. This avoids the complication of remapping or tracing setaudio references in the dvd commands.

A future wishlist would be for rebuilder to disable unchecked audio streams in the same way automatically.

I believe that is how DVD Shrink does it. No remapping - just removing and leaving a "space", for lack of a better technical definition.

If you disable the unwanted tracks in Pgcedit it removes the empty ones so you can't select them with your remote or get to them through unedited menus.

I prefer doing it this way so I'm only left with the audio track(s) I selected in rebuilder.

[jdobbs]

But that still doesn't change the menu functions that will attempt to set it, though. Do a search here at DOOM9 and you'll find reports of folks who have had problems because tracks referenced in menus did not exist (and if I recall properly, they used DVD Shrink to remove them).

Taking out those references is an incredibly easy thing for a program to do... but I'm not sure its a wise one.

I'll do some testing and see if its a good idea.

[valnar]

Any more news on this feature? I still remove those audio track references completely through DVDShrink (after a DVD Rebuild) and have had no ill effects. It would be nice to skip that step though.

[jdobbs]

You mean just removing the entries for tracks that don't exist (unreferenced tracks)? I'll take a look at it -- and if there's a way to do it with (absolutely) no harm I'll put that in.

Seems like a lot of work to run it through Shrink just for that, though... it really has no impact other than the annoying fact that they are there.

I used to Remove tracks useing DVDShrink without any problem until I did minority report. I used Shrink to remove the spanish and french tracks keeeping english both dobly 5.1 and DTS (english 5.1 being the 1st track and DTS the 3rd) I then process through DVD-RB PRO 1.08.1. During playback on my settop (Sony) After seclecting DTS via the menu- the DTS logo freeze then began to breakup, this also happen during the movie, at interval. I therefore process it again through DVD-RB this time useing RB to remove the tracks, keeping the same tracks. After this the play back was flawless.This made me realise Why DVD-RB PRO/VOBBlanker remove audio tracks the way they do. Keep up the good work Jobbs.

[valnar]

I guess I've been fortunate thus far then....

[winny]

I trust Rebuilder implicitly to do everything right, which is why I use Pgcedit as a post process step to tidy up the audio tracks. To some it may seem pointless but I see it as a tiny loose end to tidy up.

I also make sure that any tracks I remove and not selectable through the menus and disable any buttons that may reference the removed tracks, so I wouldn't expect to see any playback issues described by jdobbs previously.

Perhaps my standalone player is less fussy than others, but on the odd occasion where I've left the menu options untouched the player defaults to whatever audio track it is allowed to play.

If this introduces an element of risk then I would support jdobbs in not introducing the feature, and I'll continue to do it the manual way.
