Somebody please have a heart???...Please??

I know there are so many people having problems and I am one to add to the list.
Just when I thought I had the problem solved, BAM..I can't copy again! I tried every program that big papa recd and the ONLY
thing that worked (notice the ed on the end)
is PSX v5.0! I have an old 2x sony burner and
have succesfully copied DOA2, MDK2, NFL2k1,
Virtua Tennis. I have UNSUCCESSFULLY copied
Tony Hawk2, Soul Caliber, Test Drive la mans,
Tokyo Extreme Racer 2! I did not change any
parameters on the program. What happened?
These are all self boot games. Just when I
thought I was getting somewhere Please
