[MPlayer-users] -vo svga segmentation fault

Thu Aug 1 00:59:01 CEST 2002

Hmm... Neomagic has had some problem in the past with the Xfree server. 
If you have the money... i'd get a better card. A quick glance around 
the web suggests that there are still problems with neomagic cards and 
Xfree server... Might want to check for lastest patches for the Xfree 
server.
