right lets start at the start, after installing media player 10 i found it had wiped out all my codecs so i reinstalled the Kazaa Lite codec pack and the dolby 0x2000 audio codec.
now i find that although the codec seem to be installed properly all my files with Xvid and AC3 codecs are jumping and jittering backwards and forwards!!!
i have tried different media players and re-intstalling the codec pack but the files still dont play right
any ideas? everything worked great before… trust microsoft to bugger things up!
