I am getting memory dumps with the following errors in the XP Home Event Viewer. "DCxxMJPG video encoder initialization failed" & "Boot start or system start driver (DCxxMJPG) failed to load"! I also get an occasional "True Vector (part of ZoneAlarm firewall)" error! For a short period, the "DCxxMJPG" error kept occuring repeatedly when I scrolled to a certain point on a particular (not all) web page. It appears that defragging, disk error checking & cleaning up my system drive helps to minimize the dumps - but doesn't eliminate the problem. Can some one explain what's happening here & how to eliminate the dumps/stops?
