Track woes.

[DeVante992]

I am having trouble copying my DC backups.

I am using Discjuggler 4.01.1002-PRO2.

When I put a certain game in the drive and close it, Discjuggler will tell me that the disc either is "Unknown" or "CD-DA 2 sessions, 1 track."

So far I've tried about 3 discs.
The disc that I orginally had burned with Discjuggler 3.x comes up correctly. 2 sessions, 2 tracks.

The disc that I'm sure I originally burned with Discjuggler 4.x (not sure if it was an earlier build of 4.x) is the one that comes up with "Unknown."

I'm not sure what I burned the last disc with, but it comes up with the "CD-DA 2 sessions, 1 track."

What am I doing wrong?
Can a faulty CD-burner be the cause?
Maybe I need the exact version number of Discjuggler I burned them with? But then why would the one I burned with v3.x work?
Do ASPI layers screw around with this sort of thing?

This is quite an annoying problem. :/
