[MPlayer-users] dvd - Your system is too SLOW

[gustavo]

Hello

 When I play any dvd the mplayer write :
    "Your system is too SLOW to play this!"
and after a few seconds stop the sound and write:
    "Too many video packets in the buffer: (4096 in 8279254 bytes).
    Maybe you are playing a non-interleaved stream/file or the codec failed?
    For AVI files, try to force non-interleaved mode with the -ni option.
    a52: CRC check failed!"

What can I do.
 I have a laptop Think-Pad R-30 from IBM and on windows I can see these 
DVD,
so maybe with some flag I will can see DVD ???.

thanks
