I've installed the above named software onto my AMD Athlon XP 1800, 256, Win98SE.
It plays the DVD's beautifully, only, there is absolutely no sound! I've tried configuring all of the audio options and it just doesn't want to know. I previously had version 2.5 and that played the sound with no problems....
I run a 2.1 setup. using a Creative Soundblaster 4.1 Digital card.
