VS10+ - Completed DVD jumps back to earlier in movie

StewartTurner · Post by **StewartTurner** » Tue Mar 27, 2007 11:23 am

Hi.

I've made quite a few films with VS10+ but the one I'm working on at the moment has produced about 5 coasters so far!

I have a completed film with two video clips, and about 15 chapters in one of them. The menu has motion and transitions in it. When I watch the film it gets to a certain point (not a chapter point) and jumps back to near the start of the film. If I fast forward the film it gets through the dodgy moment and will continue.

When I tinker with the settings, re-render and re-burn the disc it seems to
vary the number of dodgy points and their position.

Any ideas?

Thanks,
Stewart

How long are your 2 video clips? And are you burning to Single or Double Layer Disc?

What is it you do when you are "tinkering" with the settings?

Regards,
George

The first clip is about 55 minutes and the second about 6 minutes. Something like that, anyway.

The "tinkering" I have done is first of all to reduce the bit rate to 6000 get the total size into the green region. The other thing I tried was to reduce the complexity of the menu by taking out the motion and transitions.

I'm using single layer discs. I wondered if the burner could be at fault but I've copied another 2 DVD's since this problem occurred with no problems.

Thanks,
Stewart.

how does it behave if you render to DVD folders and play it from there?

Your symptoms are usually related to bad disks and I did have once more than 5 bad discs (I don't remember now) in a same spindle, but still it's quite rare...

I usually render to ISO file but I could try this. The rendered AVI clips have been fine.

Actually I could try copying the vob file from the dvd to my pc and seeing how it plays after changing the extension to mpg.

The discs could be at fault since they are fairly cheap but I have used them successfully many times before.

what does Windows say if you try to Copy the whole Video_ts folder back from a DVD to your hard disk? Does it copy OK or give an error message.

What speed did it use for burning ?(I have DVD-R 8x that VS tries to burn at 16x, I need to use Roxio to burn them from DVD folders.)

Here they usually recommend not to use more than 4x.
Someone even made test and it looks like above is not 100% safe.

Depends somewhat on the player too (ECC, precision of calibration and tracking etc). Do you get the same error reading on the PC player?

Many dvd players that get an error when reading the dvd can cause this, must be in the dvd players hardware error code.

I also had a bad burn on a dual-layered dvd where the 2nd layer burn was bad. The dvd player kept returning back to the 1st layer and proceeded to play the video from the first layer, back to the beginning of the video.

To answer some of the queries:
* Copying the files did not produce an error.
* I burnt at 2.4x which is the slowest option I have access to (have also tried 4x).
* I just tried the latest attempt (seel below) in my pc and it crashed media player about 28 minutes in. On the second attempt, starting it from just before the 28 minute point it played through with no trouble.

The new attempt was a re-rendering of the video from the source files. I rebuilt the menus and re-generated the .iso file. I'll run the dvd through media player again from the start and see if I can repeat the problem.

This is about the 7th or 8th disc I have burnt. I'm beginning to think I must buy a new drive. I'd quite like the dual layer capability but I'd be upset if a new drive and new media didn't solve the problem. I've seen external DL drives for about £40 on the SVP website, can anyone recommend a good (cheap) DL drive?

Thanks again,
Stewart

Unless your using DVD+RW 2.4x burning speed seems odd for -R or +R media.

As a suggestion it's better to uncheck burn disk, create the dvd folders on your harddisk. Then play the dvd folders back using a software player like power_dvd, windvd, ulead dvd player. This way you can check the menus and videos.
After that if it plays properly you burn the dvd folders to a dvd.

I was using NTi to burn from the iso file, and it gave me the option of 2.4x or 4x, so I chose the slowest.

I've just played the dvd on my pc again from the start and it has gone way past the previous problem point with no errors! I'm not sure that playing the dvd folders from the hard disc will teach me anything until I can reproduce the error from dvd.

When creating a DVD from DVD folders, i.e. audio_ts and video_ts, do you just copy them straight to the DVD using normal DVD authoring software? I tried it once and it didn't work so I've always rendered to an iso file.

This is about the 7th or 8th disc I have burnt.

I keep a DVD-RW disc exclusivey for testing different settings and trying out new ideas. It's paid for itself many times over and I don't end up blaming my DVD Burner or Discs for what turns out to be a Rendering fault.

Yes, I have tried +RW discs too, but I sometimes find that they don't play as well as +R.

I've just burnt two DVD's - one on a cheap DVD+R and one on a Verbatim DVD+RW. Bith ran through fine on my pc. I'll try them in my DVD player tonight.

If it fails I know that there is an error which the DVD player picks up but the PC doesn't. I'm not sure what that tells me!

If it works I know that whatever the error was it has gone away. I'm not sure what that tells me either!

That you had a batch of defective DVDs?

Maybe your drive failed? I had the EXACT same problem, and, I was able to trace to the drive. It was burning, and all, but, all vids were bad, skipped, etc. Using a secondary backup drive, it worked fine..

Try burning on a second machine/drive
Play back on several different devices. ( i have DVD home theater, PS2, PS3, xbox360, and xbox, stand alone DVD player and several PC's, and an Apple network)
