[ltp] DVD plays half of the screen twice

[linux-thinkpad@linux-thinkpad.org]

Hi,

I have a Thinkpad 770Z, running Gentoo Linux 1.4.  This laptop has the
Trident CyberDVD chip.  I am also running XFree86 4.2.1, and am
using mplayer 0.90pre8-r1 to play DVDs.

The problem I am seeing is that when I play a DVD I get the right half
of the movie screen displayed twice, side by side.  Sound works, and
the movie seems to play at a good speed, but I only see half of it.

Has anyone else run into a similar problem?

Thanks,
- Chris
