I'm running Win XP with SP2. Today I DL'd and installed numerous times the 0.8.1 version. It won't play any of the dvds I have tried. I then DL'd the K-Lite Mega codec pack, installed it, but it still won't play.
FWIW, DVD's won't play in WMP either, but only because I won't pay money to get a decoder from one of the MS partner firms that sells them.
However, after installing the KLite pack, the error message changed from "no decoder" to "lower screen resolution and/or color quality settings."
I'm running out of ideas....I never dreamed watching a DVD could be such a pain.
