Hi all, I'm hoping some bright spark might be able to help me My problem is this: I've been testing running my Windows XP x64 PC with 4x1GB sticks of DDR2 and the system passes Memtest etc. with no errors whatsoever. Pretty much everything is working how it should be, except for one app... DVD2SVCD http://www.dvd2svcd.org/ If I have the 4 sticks installed, when I try to open DVD2SVCD it gives me an error Take out two sticks and it works as it should Rather than taking out 2 of the sticks each time I want to use DVD2SVCD I was hoping somebody might be able to offer another workaround So far, (apart from removing memory) the only method I've been able to find that works is to use the boot.ini, MAXMEM command, but this obviously requires a reboot in-between So would anybody happen to know how I might be able to limit the amount of memory available to DVD2SVCD, or maybe how I can get it to work with the full 4GB ??? Many thanks in advance -P
