FLV-how to play correctly?

I just got a torrented video of a flv file.Now, on windows media player, it runs too fast (the vid is a bit faster than it should) and no sound plays.AND when I tried media player classic it has music, but no video displayed :(What do I need now?(Would power dvd 9 work-i just got that and will install tommoro morning :) )

FLV? I always use FLV players to play them. One good software is Wimpy FLV Player, there may be some others that can do the job better than this but I never found any... At least I never found problems with this. :D

Ok...noted...Any converters-I may watch this on my psp-not sure if my red kawa psp converter can do it.

A good converter for near every format: Super.
