Multiple dvd recorders not readind filmd disks with anydvd

I have anyDVD 6.5.2.2 running on Vista Ultimate with 3 dvd recorders 2 on IDE and 1 SATA Sony, Pionneer & something else.

i insert on dvd film to copy with Clone DVD2 and works fine, then i insert 1 or 2 more films and then do not show anywhere: any dvd does show that there is any dvd inserted in the drive, or on my computer nothing!

but if i insert a cd or dvd program it works fine, or if i record with Nero it works fine.

so i asume there is something with ANYDVD that is not correct.

there is a film called ‘a perfect man’ which does not even show on 2 out of the 3 disks at all!

PLEASE HELP!
