Hi chazlee and welcome to cdfreaks.
By "all sides" do you mean every disc fails to rip?
If after following t0nee1's advice and cleaning the discs, they still fail,
I would send to .IFO files to Fengtao to check. He'll be able to determine if it's a failure due to copy protection.
Here's how:

1) Open an Explorer window, and navigate to VIDEO_TS folder of the DVD.
2) Copy all files ending with .IFO to hard disk.
3) ZIP the IFO files on hard disk to one file. Name it with a readable filename, like To Have and Have Not_R1.zip.
4) Send the zip file to fengtao(at)dvdidle.com, you need replace (at) with @.



I took a look online at the box set of season 1 of Adam 12. They were released in Aug. '05, so new copy protection is unlikely, but I'm not sure this is the same set?
