Empty 3d blueray?

[jumpjack]

If I put my MIB-III 3d BD in the PC BD player, I can't see anything in the media: no files, no folders.
The BD plays fine on desktop player.
What is it going on?!?

Can you see files on other bluray discs?

Have you tried install a software bluray player like tmt or powerdvd?

Have you tried a ripper like anydvd hd, dvdfab?

the obvious question is are you sure your computer has a BD-rom or a BD-writer? judging by the rest of your system specs i find it hard to believe that it does.

Problem araised since last "format c:" of my dated WindowsXp system; previously I had been able to rip this same BD, although a little in trouble with the 3d version.
Am I missing some driver? How can I know? The BD unit came with no drivers (or I lost the disk...)
It's a Pioneer BD-RW BDR-207D

p.s.
Specs on my profile are totally outdated, I should update them...
I now have a Dual Core 2 GHz AMD Athlon with 3 GB RAM, a 500 GB HD and the BD recorder.

Try install the udfreader.

Installed yesterday, today I can see the files, thanks.
Now I hope there's already a thread about ripping 3d videos, as Bino3d can't play the files in BDMV folder.
