I haven't had any probs with VLC playing everything (perhaps the odd exception.) Actually I've read reviews about wmp v's some other apps & wmp was rated better. Not to say they didn't mention some downsides to it. But most apps have their +'s & -'s. Audio/video player is whatever takes your fancy so long as it can play all 'u' want it to play (even if it means dwnlding xtra codecs.)
