HELP! ps1 backups dont work on my ps2!!!

[AhmadMasood]

hi all,

i just cant solve this problem! please help!
i have a pal ps2 with the dms3 mod chip, so EVERY country code should work. i tried clonecd and nero for the backup tests:
im having problems with following backup games: tales of destiny, lunar, star ocean (all of them get the ps1 logo on screen, but then freeze) and valkyrie profile (game boots, but hangs up everytime i try to get out of an dungeon, disc rotates very fast, but the black screen doesnt disappear).
i boot the games by resetting and holding the o button.
im a newbie, so it would be cool, if i could get some information regarding this problem.

btw: i use nero startsmart, is this a BAD idea? what programm should i use?!
