playing a video

[norman]

Usually I do not have a problem playing videos however, in this
instance, I am totally confounded. The video was downloaded from a web
site by the procedure I normally use and, when I tried to play the
downloaded file in Movie Player, my normal procedure, there was video
but no audio. I tried to play in Avidemux and again the video was OK
and, although there was sound it was fast and high pitched.

I had a look at the properties of the file and under Audio found
Bitrate: 1411 kbps, Codec: N/A, Sample rate: 44100Hz and Channels: 0.
The properties of the other files I have downloaded from this site are
Bitrate: N/A, Codec AAC 2.0 (libfaad), Sample rate: 44100Hz and
Channels: 0.

Is there any way I can change any settings so that I can view this
video, it is quite important to me?
