i couldn't figure out how to do it "natively" on my x86_64 install but 
luckily i had an identical (hardware) box with RHEL4 installed in 32 bit 
mode.  i built the mplayer/mencoder binaries on that box and scp'd them 
back to the 64 bit box, and they work.

now my next question:

although mencoder reads the wmv file, it prints tons of messages like this:

35 duplicate frame(s)!
Pos:   0.3s    271f (10%)   0fps Trem:   0min   0mb  A-V:-0.005 [0:0]
35 duplicate frame(s)!
Pos:   0.3s    272f (10%)   0fps Trem:   0min   0mb  A-V:-0.005 [0:0]
37 duplicate frame(s)!
Pos:   0.3s    273f (10%)   0fps Trem:   0min   0mb  A-V:-0.005 [0:0]
35 duplicate frame(s)!
Pos:   0.3s    274f (10%)   0fps Trem:   0min   0mb  A-V:-0.005 [0:0]
35 duplicate frame(s)!

the resulting video conversion has the video running insanely fast, or 
even just skipping whole chunks of the video.  a one minute clip plays 
back in about 6 seconds.  also there's no audio.

i did some googling and found these options recommended for someone who 
was also getting the duplicate frames messages...

-noskip -mc 0

if i use just one of them i still get the "duplicate frame(s)!" errors 
(although the exact number of frames changes) but the resulting video is 
basically the same - the video speeds by on hyperspeed and there's 
either no audio or the audio plays normally for the first two or three 
seconds.  if i use both, i don't get any duplicate frame message but the 
video is still running crazy fast.

i feel like i'm real close to getting this to work if i could just get 
the options right.

help please?
