Once in a while I get an error during the screen saver. If I click on technical details I see:
AppName: mamewah.exe
AppVer: 1.6.0.1
ModName: divxdec.ax
ModVer 5.1.1.1031
Offset: 000474fff
if I click for more details: exception information: code = 0x00000005, flasgs:0, ...
mamewah.log contains nothing of interest.
Obviously it's something to do with playing divX encoded files but it doesn't seem to be consitent in that it doesn't always carsh on a particular movie and seems to have played some of the movies just fine before.
