Editing DVD+VR causes temporary DVD freeze up, jump ahead

[Video Impressions]

I used MF4 Disc Creator to edit a +VR DVD initially recorded on my Philips 935A standalone (a process I successfully have performed dozens of times utilizing MF3 Disc Creator); this original is flawless. The edit consisted of ONLY placing 8 Chapter Stops and thumbnail replacements for the defaults the program creates. I wrote the changes to the DVD with NONE of the default parameters checked; however, I DID write in a copyright notice. When finished writing to the edited DVD, when I put it in one of my standalone DVD players (one of my Cyberhome DVD-300s), a quick check of all 8 chapter stops showed that they alll were properly recorded. The problem is that about 5 seconds before the first chapter stop I created, the DVD video freezes for about a second or two, then continues BUT SUDDENLY POPS FORWARD A FEW MINUTES INTO THIS NEXT CHAPTER. If I play this troubling section over again, sometimes after the freeze it continues at a point only a few seconds past this freeze point (in other words, my nice fade to black is gone and it looks like a badly placed cut), and other times it just jumps to the point a few minutes into the chapter! I NEVER had this problem with MF3 Disc Creator!!

What do you think is causing this anomaly? Is it the +VR edit? Later today I will try to remove the first chapter mark and reburn this +VR recording for the one change to see if this section plays smoothly, but while I had the oportunity now I thought that I would ask at this point in time.

Thanks in advance!!

It could simply have been a bad DVD-blank. Try burning again, and if it screws-up in the exact same spot, that's not the problem.

Or it could be a corrupt MPEG file. I've had "perfectly good" MPEGs that actually had "sneaky" corrption. These corrupted files would make DVDs with "lip-sync" problems, and sometimes cause the Ulead programs to crash.

You can get this sneaky-corruption simply by editing a good MPEG. But, if this was the cause of your problem, I would expect the problem to show-up at (or near) the copyright transition/splice. I don't think the chapter-points have anything to do with it.

You could try making an unedited version. That's how I finally found out that I had "sneaky" corruption caused by editing!

Both VideoReDo and Womble have tools that can repair some types of MPEG corruption. The trick is to repair the file before the final render... before the problems actually show-up.
