Hey, when I'm watching a film (just this one) with wmp11 I always get the same Photogallery Installer, wich never works, only gives errors and makes wmp crash. Is this a normal thing or what!?
No its not normal, i have no idea what might have caused it but try either:
1.Install the Divx codec (if you haven't already) free from www.divx.com
2.Get a different Movie program ie. PowerDVD, WinDVD, RealOnePlayer, WinAmp (WinAmp is free) none of these programs will work properly playing DVDs without the DivX codec.
