Forgive me if what follows looks silly, but you know I still have much to learn. I can say one thing: I remember having exactly this same problem, but much long ago, and did not solve it intentionally, upgrade after upgrade made it disappear, or installed something, but repeating, it was long ago
Answering your question above, yes and no. You wrote (15-04-2012 20:08): > The disk is SATA, so using libata.

With the iso image, these would be tested (whenever there is an equivalent) in another hardware, so if the problem (probably) remains, you are 100% sure it has to be some software problem. Another thing I notice, in 15-04-2012 13:17, you wrote: > Note that I don't have lua, I configured it with > --disable-lua --disable-libgcrypt --disable-remoteosd > > From memory, my first build was on a system that did have > libgcrypt, so that switch is probably irrelevant. As you know, DVD's are encrypted, I have no idea, but shouldn't libgcrypt be relevant? I final thought: does vlc build its own ibdvdcss? I have this installed and remember it is essential to reading DVD. -- []s, Fernando -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
