That doesn't work for me, already tried it. What I'm doing is using http://www.dvdvobtompg.com/ to first convert the VOB files to one long MPG file and then putting that on the timeline.

There are lots of ideas in this post:
Preferred DVD Import Software?
For me, using DVD Shrink ala John Cline's post works best.

The problem isn't the software, DVDVOB2MPG works great. When I play the MPG file that gets created by DVDVOB2MPG in VLC, it works fine. It's how Vegas is reading the file and playing it back sometimes. I don't know how to explain what's happening. What I'm asking is if there's some known issue with playing and editing MPEG2 files in Vegas. I'll try the DVD shrink in that thread and see if it works any better.

This DVD Shrink program isn't working worth squat, throwing up errors when I try to backup via the re-author procedure.

Did you set it to back up to harddrive, not the CD/DVD drive?

Yep sure did. I THINK I might have found a way to do this with DVD Decrypter. Tell me if this is acceptable:

I put it in File mode. Then in the settings for file mode, I choose "By Cell ID" for file splitting. And when I run it, the program creates a VOB file named like VTS_01_VOBID_005_CELLID_001_1.VOB for each of my chapters (which is a good thing because I'll need to encode each chapter to a separate file later) I can drag the resultant VOB files to the Vegas timeline and everything appears to be working fine on the timeline. Is this safe?

"By VOB ID" seems to work the same as CELL ID

"That doesn't work for me, already tried it"

In what way doesn't dragging the VTS_01_0.IFO file into the Vegas timeline not work? Is this a copy protected DVD? You need to to use DVDShrink first, then drag that IFO into the timeline.

DVD isn't copy protected. When I drag that file to the timeline, the only thing that appears on the timeline is the very first chapter, which is just opening credits.

Ok then, have you tried dragging any of the other ISO files to the timeline, such as VTS_02_0.IFO? It appears that your DVD is non standard, in that it has a video other than the main movie as the first logical video on the disk.

These DVDs were made way way back with a program called Ulead DVD Workshop 2, it was a piece of junk program that did weird things so I'm not surprised it's not working with this method. The DVD Decrypter method seems to be working though so I think I'm ok on this issue.

So, have you tried dragging one of the other ISO's into the Vegas timeline?

I doubt seriously that DVD Workshop 2 is the problem. We have burned thousands of discs using this program -- we still do, in addition to using DVD Architect -- and have never had a failure of any kind. Moreover, we've never had a problem importing from discs burned in this program.

Why aren't you using the "Import" utility in Vegas 13 to bring in material from your DVDs? Works like a charm.

Well whatever the case is, dragging the ifo files to the timeline does not work for me. And, that DVD Workshop program day and a lot of weird things. For example on those DVDs I'm not able to advance through the chapters by hitting the next chapter button. Anyways it does not matter because the solution I found with DVD decrypter is working for me. It very nicely saved each chapter to the hard drive as a vob file and I can just select them all and drag them to the timeline and do my editing. Regarding the import feature within Vegas I've read numerou threads that it does not work for some people

Just so we're on the same page, this is what you did right? I've never heard of this not working. In some cases you have to drag a different ISO into Vegas. But this has never failed to work in the past.

Precisely what I did, no go.. I'll try again tomorrow but I don't think it's going to work. Will report back. I'll do a video so you can see too..

The OP said, "I'll play something, then go back and play it again, and where there should be a fade in fade out, it's not there, but then if I change the preview quality to something else, then it fixes itself."

This looks like an inability of Vegas to play smoothly, possibly jumping over where the fade should be. Does it play properly in Vegas at less than full quality playback?

There may be some wrinkles in the video stream that other players can handle.

Try concatenating the VOB files externally using your preferred method and passing the resultant MPG file through say VideoReDo or Womble.

Lately I have been using IgorWare File Joiner to concatenate VOB or AVCHD files.

Don't include any VTS file ending in 0, since that is the menu, I think.

Are you saying that that the effects, transitions, and fades you added to the TIMELINE are not previewing smoothly?. If so, it is an entirely separate matter unrelated to your source video, and one that has been addressed multiple times.

No, I'm not talking about new effects or transitions. I'm talking about simply putting the newly created MPG from the dvdvob2mpg software on the timeline and playing through it. What i WAS doing at first was going through and manually adding markers to where the chapters start. In doing so, that's when I noticed playback did a lot of funky stuff. I thought to myself, this can't be, so I go to the hard copy DVD to the same place, and it would play fine so I knew it wasn't in the DVD source. I then went a step farther and encoded the section where the funky playback jitters or whatever were happening, and they didn't show up in the encoded file. So all I can say is that it has something to do with how Vegas is reading the MPG created by dvdvob2mpg. I haven't yet experienced this by using the DVD Decrypter method I noted above. Plus this is a better method because I don't have to go through and manually add in markers for chapters as it saves each chapter as a separate VOB that I can just drop on the timeline.

Now I'm really confused. You said that dragging the IFO into the Vegas timeline didn't work for you, to import DVD video. But this is what you did in your screen capture video, and it appears to be working fine. What exactly is it that you are saying doesn't work.

Well it is a 2 hour DVD, and the only thing that appears on the timeline after dragging the IFO over is the opening credit which lasts all of about 17 seconds :-) Had it worked, I would be expecting to see 2 hours of video on the timeline

I've had similar issues w/ Vegas not playing nice w/ some video mpeg video files.

You may want to try to re-encoded w/ Handbrake to the same settings as the original video and see if this works. Done similar thing w/ ffmpeg.

I'm pretty happy with the method I found with DVD Decrypter because I don't have to do anything regarding the chapter breaks, they are all on the timeline, ready to be edited and encoded.

I do believe that the playback anomalies were related to that program DVDVOB2MPG as I'm not seeing them thus far with the VOB files created by DVD Decrypter.
