This is the last straw. (Mac Pro with Lion won't play DVD-Rs burned on a Mac).

This is really getting out of hand. Things are just breaking one after another in the Apple world.

I have a collection of home videos that I burned to DVD using iMovie and iDVD back in 2004, on a G4 tower. My Mac Pro with Lion now does not recognize them and says I've inserted blank CDs when I put them in. I believe they were recognized under Snow Leopard.

Is this a known issue? I'm about ready to kill Apple.

did you finalize the DVD before ejecting it??

Maybe your drive is just getting old?

You can get a dvd burner for 15$ or a bd burner for a little more.

 

[swordfish5736]

have you tried putting them into another computer or a dvd player?

There is also another possibility; you made these dvd in 2004 you say? Maybe they started to rot, which is sadly a thing that can happen with some DVDs.

I've got a lot of dvds here, home made movies, old backups, ect... And for important thing I always got verbatim archival grade cd/dvd.

I have a friend who did the same, but with some cheap no name dvd spindle (tower of 50, etc...). A lot of his old stuff is not readable anymore

What i'm trying to say, I'm 100% sure its not the OS fault. Maybe the hardware, maybe the media itself, but definitly not the OS. Same thing would happen in windows and linux.

that's definitely the first thing to try.
