Ok I've installed the latest nimo's codec pack and PowerDVD but I can't seem to play back any mpv's or Vobs using WMP/Classic Player, I've also tried the Elecard player which crashes also, sometimes WMP will try and request the codec but fails. My system is only a few months old but is fully updated.

At first I thought there could be a problem with my aviscript but that plays fine in the classic player.

Also tried using both TMPGE and CCE.

Any ideas?
