"adding a track to an existing DVD w/o re-authoring the original DVD content" I have a DVD with 21 tracks on it. I would like to add a 22nd track to it. I don't want to lose any of the DVD menu characteristics. The original DVD menu authoring seems complicated to me and is best left alone (my TMPGEnc DVD Author can't author multiple angles, for example). I'm sure there are a number of ways to do this and most any way will be alright with me, so I'll start with asking how to do it the most basic way...adding a 22nd track such that I can insert my DVD in my DVD player, bring up my onscreen DVD controls, and tell it to "Play Track 22", and then it plays on the TV screen. This shouldn't change the way the original menu functions at all. The 22nd track won't even be accessible through a link in the menu...only by manually telling my DVD player to "Play Track 22". So basically I just want to append the Track 22 to the DVD w/o changing the original DVD content at all. To simply add the Track22 .VOB to the original DVD's VIDEO_TS folder won't work of course. Creating a DVD is much more complicated than that. You also need the .IFO files to recognize and reference the extra track. Can I just add the Track22 .VOB and its corresponding .IFO while editing the original DVD's VIDEO_TS.IFO such that a DVD player will recognize the extra track?? Here's the original DVD's content: VIDEO_TS.IFO 12kb VIDEO_TS.BUP 12kb VIDEO_TS.VOB 8kb VTS_01_0.IFO 230kb VTS_01_0.BUP 230kb VTS_01_0.VOB 446,656kb <--- all the orignal DVD menu content.

And I've been slightly misleading up to this point. The reality is that I know that b/c of disc size limitations, I'll have to eliminate some part of the DVD's original content. The good news is that the last part of the .VOB's (I'm referring to the end of VTS_01_7.VOB and the entirity of VTS_01_8.VOB) contains a track that I'm not interested in at all. So I was thinking I could just truncate the original DVD content...or patch the new .VOB conent over the original DVD .VOB content, right down to the frame, so that the DVD player wouldn't know the difference. Thanks in advance everyone for your help or any useful links.
This is absolutly not Possible at least not with a DVD+R or a DVD-R, Firstly after the DVD has Been Burned and Finalized you can not add anything to it...Even if the Disk has not been finalized the only way to add more data to the disk would be to make a Multi-session disk and DVD Players can not read Multisession disks.... Also the IFO and BUP files would have to be Changed to reflect the new Video Content and you can not selectivly go on to a DVD and edit the Content of one of it"s Files.... If the Disk was an DVD+RW it could be edited in a sence but invariably you would simply be ripping the data off of the Disk and then adding to it and then Burning the Data Back to the DVD+RW which is basicly what all of the programs that support On disk DVD editing do...... Cheers
There seems to be some confusion here. When I say "DVD content", I'm referring to an exact DVD copy on my hard drive, not the original, physical DVD disc. I may be a bit of a newb, but I'd have to be a stunningly clueless newb to not know that you can't burn new content onto an already closed DVD disc (or DVD-R w/o making it multisession), lol. I see now why you thought otherwise. I kept using the words "my DVD" and you probably assumed I meant "my original DVD". I just meant "my newly burned DVD-DL". I completely realise that I'll have to reburn this DVD's contents (with my added video content) onto an empty DVD-DL. Interesting. I'd assumed that something like "IFOEdit" could edit an IFO to my heart's content but you're telling me that its ability to change the info within an IFO is very limited??? (no ability to manually add reference to another added track, for example) UPDATE: I went and tested out IFOEdit more fully. It seems it is pretty limited. Is there any other software that will let me edit .IFO's more fully?? My understanding of DVD content is that the .VOB's are like raw video data and literally contain NO information about the setup of the DVD. That means that no matter what .VOB's are in your VIDEO_TS folder, if you can create or edit the corresponding .IFO's properly, you're good to go. Right or wrong?
UPDATE: I've done some experimenting. EXPERIMENT#1: When I replace the original VTS_01_8.VOB (~230,000kb) with my new .VOB (which is ~240,000kb, which I also named "VTS_01_8.VOB"), my DVD player plays the disc just as it always did, menu and all, but when it gets about half way through Track21 the video seamlessly switches to the newly added video...but without any sound (presumably b/c the original DVD is all in 5.1 AC3 and my new .VOB is in MP2). ...and it cuts off about 10 seconds before the true end of the track (presumably b/c the new video content is 10 seconds longer, but the corresponding .IFO's haven't been edited and still expect it to be the original length). EXPERIMENT#2: I ripped the entire 16-min. long original Track21 (which is composed of the end of VTS_01_7.VOB and the entirity of VTS_01_8.VOB) and reauthored it as a new .VOB (~591,000kb, audio as 5.1 AC3 this time). Just as I did before, I renamed it "VTS_01_8.VOB" and switched out the original DVD's VTS_01_8.VOB with the new, much longer one. Then I tried to play Track21. As expected, halfway through Track21 it seamlessly switched to the new video content but this time it had audio too! However, it still ended prematurely, this time several minutes premature since the new "VTS_01_8.VOB" was several minutes longer than the original one and the origianl .IFO's still hadn't been changed. What all this tells me is that if I wanted a quick and dirty method to add my additional video content, I could just encode my new video as a 5.1 AC3 .VOB named "VTS_01_8.VOB" (while deleting the original VTS_01_8.VOB)...and as long as it was shorter than ~230,000kb, the DVD player would switch to my new video content about halfway through Track21 and would play it in its entirity, with video AND sound. However, that's maybe just a little TOO "quick and dirty" for me since it would require me to fastforward through ~8 minutes of the old Track21 content before getting to my new video content. Let me add that I'm not capable of encoding to 5.1 AC3 or even 2-channel AC3. That could be a problem. The only reason my new video content was AC3 in experiment #2 is b/c the audio was already in AC3...I never had to convert or encode it. Is it possible to create a readable DVD that has AC3 audio on some tracks and MP2 audio on others?
Well I was under the Impression that you wanted to add content to an allready Burned DVD-R.... You can edit the Content of a DVD useing IFO edit or even DVD-Shrink in "Re-Author" mode.... Cheers
I found this statement on another forum which suggests that .VOB's are not like raw video data; they also contain "VOBU pointers".
