Hi loosie,

there are many of dvd recovery software but trial versions will not do until they're fully registered..

I've tried:

CDRoller 6.4
IsoBuster Pro v1.9.0.3
IsoBuster Pro 2.0
Bad CD Repair Pro v4.06
CD/DVD Data Recovery v1.0
CD/DVD Diagnostic 2.0.2
File Recovery Pro v7.0
FileRecoveryAngel v1.13
FinalRecovery v1.4.0.1

and few others for which I had no reg info (only try but with no success)

I recommend IsoBuster 2.0

Wish you luck..
