Anyone use the DRU500AX

[ssforu]

I have the DRU 500 A with the latest firmware (1.0g)
With the older firmware (1.0e) I made working backups of my games NBA2003, Splinter Cell and Micro MAchines.
After upgrading the firmware every game I tried to backup (FIFA2003, CmRAE3, DOA3) doesn't work on my XBOX (evolutionX and Xecuter 2 Lite installed). I usually get a blank or blue screen and nothing afte that.
I use FlashFXP and XISO and eveything seems to be going OK.
I tried Recordnow and Nero with the same results.
Din't try yet to backup again NBA2003, Splinter Cell and Micro MAchines.
Any ideas?
Is there a possiblity some games to be copy protected?
