Hi Stefano,

Not to ask a too stupid question, but did you check your md5sums?

b37209879c0fb158fac25045527241ee  CentOS-5.6-x86_64-bin-DVD-1of2.iso
3eb277f8ca8d49cc8fcaf76d647169c4  CentOS-5.6-x86_64-bin-DVD-2of2.iso


Also, I find in Virtual Box, that mounting the ISO's as a DVD/CD device 
works
better than using a loop back device.  From the Console,

1st:  file, virtual media manager, attach your two iso's
2nd: go to the VM's icon, Settings, Storage, connect a IDE port to both 
ISO's

Also, Virtual Box is riddled with bugs.  Try posting on their forum and see
if anyone else is having the problem.

HTH,
