Madonna The Confessions Tour
I've encountered the same copy issues as you, poor video quality, out of sink audio, and skipping. I've send the appropiate .ifo files and and explaination of the problems to: firstname.lastname@example.org
I found these instructions on this forum:
If you're absolutely positive you've encountered a new protection, please follow these instructions (originally written by Olli):
1.) DISABLE AnyDVD (little fox on the taskbar should be grey).
2.) Navigate to the VIDEO_TS folder of the DVD.
3.) Copy all files ending with .IFO to your harddisk. ONLY those with .IFO, not the big .VOB files!
4.) ENABLE AnyDVD again (just in case, so you don't forget it)
5.) ZIP the .IFO files to one file. Name it with a cool filename (e.g., Little_Black_Book_UK.zip)
6.) Write a an email to support(at)slysoft.com (replace (at) with @). Name your problem, try to identify the disc (e.g, Little Black Book, R2, UK), the UPC number if possible (below the barcode on the package). The information output of AnyDVD can be helpful as well.
7.) They like if you include the AnyDVD version and your AnyDVD serial number in this mail. You find this information in the Settings Window -> About.
8.) Attach ZIP file with the IFOs and send it.
I followed these instructions, but I would suggest you do the same thing, so that the support team will have two verifying sets of .ifo
I was able to make a flawless 2 disk set using the chapter editing...I broke it up into Disk 1 with chapters 1 thru 11 and Disk 2 with the rest.
You can also make an excellent copy using a Dual Layer DVD. It is my guess that with the amount of video and audio information on a two hour concert that there is just too much information to make a decent single layer DVD backup.
