Never seen a problem like that.
Maybe bad video file, or there is a bug in the codec used by that file.
Given multiple players failing it is likely a codec bug or a problem
with the file (since most of the players share many of the codecs).
Of course it could be a bug in the nvidia driver too related to the way
the video data coming out of a given codec is processed. I believe the
x11 driver, all the processing is doing by the player/codec and fully
decoded video is sent to the video card. With xv a lot of the decoding
and conversion (YUV to RGB and all that) is done by the video driver or
hardware, so there certainly is a possibility of different behaviour
there.
