Interesting.......
Purchased a concert DVD once on
ebay, and it was a bootleg !!!
DVD-R...
However he did a good job on this, the case was printed up to look real, the sticker on the disk kind of looked real, however the video on play back was compressed to a DVD-R from a DVD 9 disk.
Wouldn't have cared that much, but when I question him on this, he claimed it was real, so I started emailing all his customer that he was selling fakes and how to tell they were fakes. The purple liner on the back of the DVD was a give away and also the DVD-R printed on the inner circle.
"He fooled all of his customers, not one of them knew they purchased a pure bootleg of a real recording" Until I told them
He refunded the money and kept the bootleg DVD.
What I am saying is this, eventhough the DVD make look real it could be a fake......
Audio Video Sync Problems can be kind of funny. It can also be the DVD player, that has a hard time coding the audio.
It could be your setup.....
Lets say it is the DVD.....
You have to break down the video to the frame and than try to find out were the error is.
If it is simple like off by 5 to 7 frames, you re-sync it, if it is a random pattern of frames off in different sections, you are going to have problems.
Sometimes a video will start in sync and by the end it is off by more than a few minutes......
Lets say track 8/chapter 8 on the DVD is out of sync from the start, but than you start the video on track 8/chapter 8, the video/audio is in sync, than 10 minutes later it is out of sync again.
Would have to look at the actual file aka the DVD to tell what is wrong with it.......
