Need dvd/cd diagnostic tool recommendation


Can anyone recommend a good (preferably free :stuck_out_tongue: ) DVD/CD diagnostic tool?

This is basically what I need:

CD: 1. Can read and display ISRC information per track (I tried using TAU but ISRC’s displayed per song are the same. Should be different per track)
2. Can do a spectrum/frequency analysis per track
3. Can read and display any or all information of p and q track

DVD: 1. Can display which disc layer information is embedded on (0 or 1) if not on both layers.
2. Can display which software was used for the master…

Would really appreciate any recommendation. Thanks :bigsmile:
