iBook G4 spits out all DVD's

[Gil]

Just recently, my iBook G4 spits out all DVD's without even reading them. CD's work just fine, and it's a Combo drive, so why would it be doing this? If I put the exact same DVD into my USB DVD Burner, it reads fine... But the internal Combo won't read any DVD's.

Any ideas? :?:

If it's spitting out factory-pressed DVDs (I'm taking your "all DVDs" literally), then your drive is likely toast. Dual-laser drives use an IR laser for CDs, and a red one for DVDs. The red laser is the more fragile of the two, and if it dies, you get the behavior you're observing.

Now, I don't know if your drive has two separate lasers, but many do (in order to maximize compatibility with the various flavors of recordable media).
