xvid movie is running too slow

[encman]

hi thiis is my first post,so i´m going to try to be as clear as possible.
i downloaded a film via p2p and AVICODEC tell me this:

Video : 612 MB, 906 Kbps, 25.0 fps, resolução 608*256 (2.21:1), XVID = XVID Mpeg-4, Suportado
Audio : 87 MB, 129 Kbps, 48000 Hz, 2 canais, 0x55 = Lame MP3, Suportado:
Some words are in portuguese be i think its acceptable.
Even so i have xvid codec installed , when i play the movie with power dvd 5 it runs too slow or even freezes..Video and audio are not sinchronized.
I´m really tired of power dvd.Some people say its a good movie player but the same problem happens with WMP. My pc is running well(when i say this it starts to crash). What do you magicians suggest:using virtualdub to extract the sound,erase xvidcodec and install again...

try play with vlc media player. if you still get audio sync problems is probably the source baaaaaaaaaaaaaad.
