You can only 'fix' it by reburning the disc. However, exctract the 'broken' DVD with DVD Fab Decrypter (get the freeware version, just Google it), then copy the content of the entire VIDEO_TS folder to another disc (choose to create "DVD Movie" and put all those content into the destination's "VIDEO_TS" folder too) then burn the DVD.
In most cases, it will help. If it still doesn't help, nothing will.
1/. Install the upgrade for Fab Decrypter.
2/. Make sure the DVD disk is clean and free of scratches.
3/. Use a grade 'A'/brand name media. The cheap media used at places like pacific mall is a low grade disk and it may not play in your Ps2. I know a guy who has the same problem when he plays these DVD movies in his xbox, reglar DVD's work fine.
4/. Maybe the original Clone master you had to copy from was defective.
5/. Can you play regular DVD's in your PS2?
6/. There is a chance your laser in your DVD burner and/or your PS2 is the problem. # 1-4 are more likely.
DO NOT touch the laser, if you do it will not be in alignment and you will have more problems reading DVD's than before.
