merging 2 DVDs into 1

[namsilat]

I have 2 DVDs from which I have a ISO file for each. They look to be small enough that 2 can be burn onto a single DVD. Is there a way for me to produce 1 ISO file out of these 2, or burn these 2 ISO files onto a single DVD? I tried Alcohol and Nero, but I couldn't find a way to this.

Before shrinking them, I need to "join" them first. I don't think I need to shrink the final product anyways, the 2 ISO files have a total size just enough for a single DVD..

Either way I tried DVD Shrink and it did not work out. DVD Shrink could not even read the DVD, something about error in the "navigation structure".

With Nero, using Nero Express, shouldn't you be able to drag the two ISO files into the Video Folder, then burn the DVD and it will play the two seamlessly?

But, if you want the two files on one DVD but be independent of each other, with a menu to choose between them, then you need to be authoring, in which case you need to be working in Nero Vision. In that case I'm not sure the ISO files will work, though.

I tried that by selecting DVD Video, but an error message pops up indicating it will not take a file size greater than 2 GB. If I just drag the VIDEO_TS folder, then the 2nd one over-writes the first one. I am just looking to have the videos from these 2 ISO files linked together, I don't really want separate menus or fancy stuff.

Use DVDshrink3.2, file mode, and browse to first vifeo_ts, then choose re-author, and pick the main movie, THEN browse to the second Video_ts folder, and select the main movie in the folder, THEN do a "no compression" into a new movie.

The two videos will play one after another, once you pop the disc into the DVD player.

Take some patient, and go thru the useful options of DVDshrink3.2, so you can get it done.

I think there is some problem with the DVD structure of these 2 ISO files. I tried your suggestion, and DVD Shrink only showed menus and a "main movie" that's not the main movie. The main clip is no where to be found.

I managed to use TMPGEnc' DVD Author and added the main movie clips from both DVDs, but unforutnately subtitles did not come with them. This is probably the closest I have got, if I can get the subtitles working then the job is done.

In general, if you can watch the entire video, then it can be extracted, because able to watch it confirm the video is compliance to DVD standard.

If you can use TDA to join them, implied the vob files are good. if you want subtitle, then use vobedit to join the vob files, and use ifoedit to generate the ifo files, and then use subedit to define the subtitle for the look you want.

ok just to trouble you with another newbie question. Usually in what file type are the subtitles stored in a DVD? How do I know where to look for the files with subtitles?

The subtitle is embedded inside the vob files. Subedit will figured it out itself.

I have been fiddling with this for the past few hours and I must say I am so frustrated with this I am ready to give up. I used DVDSubEdit and it displays the subtitles ok (there is only 1 stream anyways), I thought it can "imprint" the subtitles into the video to make it part of the video, but I honestly can't tell if DVDSubEdit saved anything. I plan no modification to the subtitles, just simply want to see them displayed. I tried reading DVDSubEdit's user's manual but it didn't really help.

If the subtitles are part of the VOB files, why does TMPGEnc DVD Author program doesn't include subtitles in the process re-authoriing?
