Blargh, Blimey, RAM, DVD

In linux on December 13, 2009 at 6:34 pm

Okay, lazyweb:

Why can’t I play DVDs and why, when I have installed in my computer two RAM modules of 2GiB each, does my computer have 2.9 GiB of the RAMS? Why?

On the DVD end, I have installed one million things and gotten from an error in Totem (“no uri handler implemented for dvd”) to Totem quietly crashing when I try to play a DVD. VLC spins the disk and then stops. /var/log/messages shows this after trying to run VLC:

And after VLC quits I see a whole lotta this:

You can see how this might get frustrating. I’ll let you know if I get anywhere.

  1. The last time something like that happened to me, I had forgotten to install libdvdcss2.

  2. Sadly, libdvdcss2 is decidedly installed. I did have to install regionset, though, and then set the region. Now I can kind of play a DVD, but the actual playback is really, really choppy.

I don't have a comment policy, for better or for worse. If I really feel insulted by a comment I might take it down, but I'll always tell you why. I always flag cyrillic comments as spam even though I can't read them so technically I have no idea what they're about. I apologize for that business about comments being a "privilege" -- my penance for using a template out of the box. Rest assured that it is my privilege to have you here!
