Well, it's loading and playing, but the playback is shotty. Not likely to be copy protection issue in there since it copied (unless they've got some wierd macrovision type crap they're trying now).
Gotta look at this just like a movie. Your transfer rate is too low, or the data itself is getting corrupted. Unless you have a bad chip somewhere, it's likely got something to do with the transer rates: could be from the source, to the blank media, or from the blank media to the PS2. A few things to suspect: Poor quality media, dirty/scratched disks (source or copy), dirty/weak lasers (in reader, burner, or PS2), under-powered/misconfigured system.
You need to do 2 things:
1.) Clean your source disk and all laser heads with a cleaning disk. You may even need to run it through a disk doctor if it is heavily scratched. Recreate your image on your hard drive and read that image at MINIMAL speed. You did image it to the hard drive first, right? "On-the-fly" opens up a whole lot of problems. One of which points to the "underpowered/misconfigured system" issue--many people have the reader and burner on the same IDE cable, on top of each other, and sharing the same power cable. This is three strikes against you if you are burning DVD on the fly. Regardless of your setup, Source should ALWAYS be imaged to hard drive first--too much room for error from too many different issues to explain here.
2.) Test your media to make sure you are burning at the right speed for your media. This is VERY imoportant. I have personally seen a 1X burn play like crap, while a 2X burn on the same media plays like a dream. If your media passes for 2X and you've done a 1X burn, go 2X--and vice versa. There is a link stickied up top about this.
**Some burners may need a new official or cracked firmware that allows 2X burning on capable media that must be installed to burn 2X--especially with off-brand media. These discs will have poor playback at 1X on load intensive games. The only way to correct it is to move to a 2X enabling firmware. Without this, they will scan as only 1X capable media because the drive doesn't accept the mfg. ID as being 2X capable--this will only be corrected with an official upgraded or cracked firmware. The same issue can exist with 4X media as well. Sometimes 2X is the best choice for them--it comes down to a little trial and error sometimes. You can get most of the popular firmwares from DVD-Recordable:

If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
