i get sort of the same problem except that i get a blue screen everytime i shutdown or restart, the drivers i got were from dvdutils.com that were from sigma for the hollywood plus and win2k, b4 i used the drivers everything went fine.. i could play movies if i used dvdplay from ms, only if i had WinDVD istalled otherwise it would not detect the card.. so the only thing the drivers changed were that annoying blue screen, and even after i unistalled the drivers i still get the blue screen, im thinking of formatting just to get the screen to go away ..i'll try some other fix meanwhile ..if i get anywhere i will post.
