Trying to copy a DVDR-produced DVD using K3B on this 42.3/KDE3 system causes the CPU to peg and K3B to freeze. It also exhausts free RAM. I have to exit the KDE session to normalize the desktop. If I only want to burn an existing .iso to DVD, then K3B works as expected. A month or more ago, K3B always worked as expected.
So I tried to use a different 42.3/KDE3 PC to see if it would work, and K3B complains about MAD not being installed. When I try to install kdemultimedia3-mad, zypper complains nothing provides mad. On this system, there is no current "mad" available, only as you can see here: i | libmad0 | package | 0.15.1b-4.1 | x86_64 | (System Packages) v | libmad0 | package | 0.15.1b-2.1 | x86_64 | Update
I don't know why the current libmad0 is shown as an older version than that installed.
About mad, I filed a bug: https://bugzilla.opensuse.org/show_bug.cgi?id=1076935
I gave up enabling mad on the other PC and tried with K3B to copy the DVD, which should have nothing to do with mad anyway. It too pegs the CPU and writes 0 bytes to the tmp file. On the first attempt, I did Ctrl-Alt-F3 first to run top. On return to KDE3, K3B had disappeared. On the second attempt, after several minutes of 0 progress K3B simply disappeared. Third try I logged in as root to run K3B with same failing result. On the 4th try with a different DVD made with a different recorder, the K3B crash aborted the KDE3 session as Xorg process was killed due to RAM exhaustion.
Does K3B DVD copying work for anyone here who has 42.3 fully updated?
