Would this work for a DVD game?

[Holomatrix]

Hi, I have this interactive game on DVD called Dragon's Lair, which has a bunch of ifo's,bup's and vob's. Can I encode the vob's to CVD (keeping DVD compliance) w/ 224 bit audio and VBR, then rename the mpg's back to vob after encode then burn eveything back to a CDR as a DVD? The whole disk is 2GIG so by encoding the video parts to CVD should yield me enough compression to fit everything back as a DVD on one CDR????
Thanks

So are you saying you want to make a Mini-DVD (DVD on a CD)?

[Holomatrix]

I guess. If a mini-DVD is a full size CDR and not those two inch round high capacity disks.

[Holomatrix]

I just checked the Doom9 guides and he has one called miniDVD guide but looks complicated - ( You need the following software for this guide:

Ripping and encoding utilities (requirements stated in the SVCD guides)
DV Tool
Vobsplit
StreamWeaver - part of DVDMotion Pro. The manufacturer no longer offers a free demo of that product. Homepage
DVD QuickBuilder - The manufacturer no longer offers a free demo of that product. Homepage
Nero - NOTE: Demo version, you can buy the full version online. Homepage )

Wouldn't the way I stated above work ? I don't understand why i would have to go through all that stuff. - ((mini)DVD guides

There's 3 parts here: Authoring guides will teach you how to author your own DVDs from scratch. Encoding guides will tell you how to create DVD compliant video streams and IfoEdit guides will tell you how to strip streams and extras from DVDs in order to burn them onto DVD-R/Ws without much further work)

Thanks

hollow i don't see why your method wouldn't work as long as you kept the dvd compliance...maybe make the standard mpeg2 file and burn it or check it with a dvd authoring software just to make sure it is dvd compliant.

best way is to try i guess, since nobody else seems to know :)
please let us know

[Holomatrix]

I guess I could try it. Just wasn't sure if the VOB files on the DVD have some proprietary header info that I would need/missing when renaming my encoded CVD mpeg's which would cause the ifo's/DVD player not to recognize these new VOB's ?? but I could assume that if I use NERO to burn a DVD CD then it would add the necessary compiling information that is needed. Wait a minute, I just looked at my NERO 5.5.8.2 compilation window and there is no DVD option, what version of NERO does DVD's or is there another program that I could use to make the image?

maybe this helps a bit:
first get some knowledge about ifoupdate and ifoedit...
(DVD-9 to DVD-5 "full copy" instructions)
then you have to put each .vob set into dvd2avi and save it as a dvd2avi project..now since you want to put it onto 1 cd you have to do some maths ,cause you have to calculate the bitrate for each .vob set,cause it have to fit onto a cdr..than encode everthing in cce dvd-compilant..then reauthor ,and do it like in the guide "DVD-9 to DVD-5 "full copy" instructions"...now you can burn it with nero as a "udf\iso" disc than you should have a mini dvd...

but im not sure if this works,cause i don`t know the structure of the game dvd....and keep in mind that a ac3 stream is very big ,and you only have 700mb on one minidvd(not like svcd),and make sure the standalone can play minidvd..

if you plan to do a normal svcd(cvd) which behaves like the original dvd it will not work,the only thing which is possible i think is to put only the video sequences of the game on svcd....

so far ,hope i was a little helpy:)

The GAME only has an empty AUDIO_TS and the VIDEO_TS folders. The VOB's in there are only like 100 meg 200 meg ... 5 of them (2 GIG total) so should be able to compress using CCE no problems. I'll read the guide that you mentioned. also encodeing the VOB's as CVD sould be more compliant then SVCD, right? or should I not worry about that and just encode the VOB's as SVCD and add everything to my udf/iso compialation?

[orbit-r]

hi,
what i ment with "the structure of the game" is like that:
if you press "play main movie"(on a movie dvd) it plays usual the first .vob set complete cause it holds the main movie,but i don`t know
how a game dvd behaves f.e. if you have two options in the game it can be that it that the one option is in a other .vob set than the other...

but since some movie dvd`s have this too (and i managed it to burn it to dvd-r:D )i think its possible to do that for a game dvd...

so far ,since a mini dvd is dvd,you can`t use svcd size,otherwise the authoring prog. will complain,use the half d1 resolution..
and you can`t put the .mpegs created by cce into nero if making minidvd...you have to use "the guide mentioned above" for every .vob set...
in the end you will have a VIDEO_ts folder,which you put in nero as udf\iso and burn than...

Ok, thanks. Yeh, I was reading the guide and I am probably going to have to do everything, to sync the ifo with the new mpeg and add chapters and subtitles(the subtitles are probably the pictures that pop up at the bottom of screen that tell you when to make a moove) oh well, still reading :) and yah, the game would probably switch between vob's like when you die or select the right option to continue. I hope I didn't get into somthing to weird to backup to CDR :) :)

[orbit-r]

let me know about the results...

[Holomatrix]

ok, will do. I was hoping to just use DVD2SVCD doing CVD mpegs enabling Subs and original Chapters then use the original ifo's with the new mpegs and create a udf/iso.. bing, bang, boom :) I guess I will do some testing. :) should I enable the DVD compliant option in CCE and DVD settings for bbMpeg?

[Holomatrix]

I can't find DVD Maestro, so was wondering if someone can let me know if I let DVD2SVCD create my new mpeg/vob's will the original ifo's still work? not sure what info is stored in the ifo.
Thanks

[orbit-r]

i don`t think this will work...
you need maestro...

[UltimateDBZ]

No, a Mini-DVD isn't like those (stupid) Mini-CDs, the 2 inch things. It's simply DVD content on a CD. Keep in mind though that very few standalone DVD players support Mini-DVD playback, if I remember correctly.

[Holomatrix]

Ok so, tried a regular DVD2SVCD convert of the VOB to CVD, re-named the compressed mpg back to the original VOB name and tried to run it with WinDVD (using the run from folder option) since I have everything backed up in a folder. Right when the Game gets to the part were my "VOB" is, low and behold WinDVD crashes :(

So, I guess I am going to have to try the long way DVD9-5, if I can find DVDmaestro somewhere :) PM, PM, - oh excuse me :)

[Holomatrix]

Ok, I've managed to get the software I need :) :)

When I boot up Maestro, I get this error -'Real time preview funtionality will not be available because no decoders have been detected' were do I get the decoders?

Thanks

[orbit-r]

hello,
1)when encoded as 4:3 let it at 4:3
2)use chapterxtractor for getting the the chapters out of the vob`s...
and you have to double click on "movie 1" this will pop up your
timeline,drag there yoor .mpv and .ac3,than right click on the line above the movie line and select import chapter list(made by chapter xtractor)...
3)this is normal you need some .dll`s for preview function in maestro..but its not important..(ypo can check the compiled dvd on win dvd) i ve lost the url for dll`s ...i let you know...


good luck ;)

hehe, sorry I just edited my post while you were typing yours. I figured out how to get it going and compiled it :) Yeah, let me know if you find thoes dll's :) Thanks. Now that I've figured this part out I need to get back home and finish with the real thing. (Testing at work with some other vob's I have)

[Holomatrix]

Oh, well. Does not work. Everything seemed to go ok, except this after compile - 4 Warnings :
- No First Play assigned.

- Menu Menu1 : No Background Image defined, use default blank image!

- Menu Menu1 : No Buttons defined!

- Menu Menu1 : No Subpicture defined, use default blank subpicture!

but ignored it. The guide also says this - "Now is the time for the real magic! The ability to incorporate your new files back into the original DVD structure so it will be just like the original with menus and all! The first thing we want to do, in this example, is rename our authored VOB files to VTS_02 instead of VTS_01. They are going to replace the VTS_02 files in the original. DO NOT copy over the authored IFO file! DO NOT copy over the VTS_01_0.VOB file! Remove all of the original VOB files (You MUST leave the IFO file and the VTS_02_0.VOB files!) and copy over the new ones in their place."
Which does not make any sence, Leave the files/Delete the files/Leave the files/Then copy the new ones ???? stupid

What are the files I need? I have seven VIDEO_ifo. bup...VTS_01_1 ...

The origianl VOB does not even show the little pictures at the bottom right, which tell you when to make a move. I don't know were thoes subs are. There are five sets of movie VOB's and was just trying to merge in one set to see if I could do it. Oh, well, F**k it. Thanks to everyone that help.

And the audio is ahead of the video by about 2 seconds too :(

@orbit-r - still wouldn't mind thoes dll's though :)
Thanks
