Seems to be a Nero bug too.
I've 2 PC and frequently exchange data per CD-RW between the 2 machines.
Well, here is the problem:
Some time ago I had Nero 5.5 on both machines (all versions worked than)
and created multisession CDs with CD-RW media.
But I recently updated Nero on one machine to Nero 126.96.36.199 and since then I can't continue any Multisession disks created with Nero 5.5 nor can I continue any multisession disks created with Nero 6 on my Nero 5.5 PC.
Additionally I can't delete any multisession CD-RW on Nero 6 which were created with Nero 5.5 and vice versa.
If I try to continue the Nero 5.5 multisession Nero 6 says 'failed EndTrack'
And if I try to erase it, then I get 'ain't no CD-RW'
Even if I erase it with Nero 5.5 completely Nero 6 states that it wouldn't be a CD-RW.
Is that poor policy or what? Not upward compatible I could understand but not downward compatible?
Drive on 'Nero 6 PC' is Sony CRX210E1 and latest firmware
and drive on 'Nero 5.5 PC' is LTR52246S with latest firmware
Hope that bug is fixed with the next update!
