Hi!

Can anybody help me the next situation:

A installed mythbuntu 8.04 on my htpc.
My pc hardware the next:
Processor: Athlon(tm) 64 X2 Dual Core Processor 4200+ processors (2 cpu cores)
Motherboard: Asus M2A-VM HDMI (with integrated ATI VGA, but not use,
because poor quality)
VGA card: MSI NX8500GT-MTD256EH/D2 PCIE
RAM: 2GB 800 MHz DDR2
DVD reader/writer: SATAII Pioneer DVD-RW  DVR-212D
Hdd: SATAII Samsung 500GB

Uname -a out:
Linux myth 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux

The problem is:
often the mythfrontend stopped, and segfaulted when started to view
the dvd movie or audio cd. The messages contain the error:
