824 MB VIDEO_TS is nothing but FBI Warnings?!

After ripping the new version of Texas Chainsaw Massacre, (NTSC region 1), I noticed that video_ts was an ungodly size. Upon further inspection with MenuEdit, I noticed that other than a studio logo and miscellaneous blank cells, every other cell was a video clip of an FBI warning!

What a waste of space! By replacing these cells, I got the size of video_ts to just over 300K.

Just wanted to post it in case any one else is backing up this DVD. The video quality is much better with nearly an extra gig of space!

This is actually becoming more and more common... I just did one the other day that was 1.6 gig VIDEO_TS that was nothing... in fact.. the cell was never used in the dvd (numenu took care of it nicely)

yeah.. since the studios have a bitrate that they seem to encode video ( im thinking they must figure it out based on quality (ie quantizer) and if they end up with free space on the disk they fill it with junk since once they have gone beyond the dvd5 size it doesnt cost any more to fabricate the disk that is more full. xmen 1 is like that.. i think it was almost 2gb between several vts'.. i noticed on another fox video...cant remember which.. TCM is newline so i guess i need to watch for them as well...

I really wonder...what exactly is the point of doing that?

Exactly like trahald said.... filler

I imagine also the greater the data "used" amkes it more difficult for standard users to make that image fit to a DVD-5

It's mainly a lame attempt to make the disc bigger and to make life harder if you want to make your own personal backup.

This has been surfacing a couple of times, ever since the lion king if I recall correctly. if you do not examine your disc well and you keep all that filler stuff you'll end up with a very low bitrate for the rest of your disc.

And as shown in the example above, you can easily save space up to more then a GB!

Yes I've noticed this alot too. My theory is that they try to match up the size of each layer so that it minimizes the distance it has to travel on the break, to minimize the pause. Seems like they shouldn't have to use large filler vobs to do this but maybe there's some limitation in their authoring software or something.
