Did you tried Oplayer ?
Didn't tried it with wmv but works perfectly for me on my iPad 1, with mkv and other formats, even with subtitles. I would love to try it on iPad 2 to see if the new CPU handles 720p videos :)
VLC for iOS was promising before it was removed... sigh. :/
Update 2018: VLC for Mobile is available in Apple Store.
I finally found the exact combination I needed, and I found it in ffmpeg.
I will expand on the question a bit and spell out the fact that I was already working with mp4 contained video/audio, so MP4 Video (.m4v) and AAC Audio (.m4a). I absolutely wanted an as-is version of the audio extracted from the video.
First off, it's pretty easy to install things like ffmpeg, mplayer, things built off them, and similar open source packages nowadays. Between Rudix, Homebrew, MacPorts, and Fink (does anyone even use fink anymore?), third party software is a snap to install.
So, after installing ffmpeg, and having the ffmpeg
accessible at the command line, I ran a command like this:
ffmpeg -i videofile.mp4 -vn -acodec copy audiotrack.m4a
ffmpeg: The command.
-i videofile.mp4: The source video file.
-vn: Do not record (do not consider) video data.
-acodec copy: Copy the audio source as-is, here's where all the magic is. ffmpeg will write the audio data out as various supported codecs, but specifying copy leads a bit-for-bit exact copy of the stream. Coupled with disabling video via -vn leaves you with a lone audio track inside an mp4 container.
audiotrack.m4a: The output filename.
I can't believe something like this was so difficult and hidden for so long.
Since I always intend to rip aac audio data out of an mp4 container/video, I wrote a quick little script to do it.
#!/bin/bash
INFILE="$1"
TMPOUTFILE="${INFILE%.*}"
OUTFILE="${TMPOUTFILE##*/}.m4a"
ffmpeg -i "${INFILE}" -vn -acodec copy "${OUTFILE}"
Now, I simply invoke rip_m4a_from_mp4 somevideofile.mp4
and I am left with an audio only version with the same filename, ending in m4a instead.
Simple! For me anyways. No GUIs, lightning fast, this is just one of those things that the command line does better.

I found some background to this - Why cannot Pages show pictures in .rtf files? that Apple decided not to support pictures in rtf because of limitations in the format, but instead to opt to use rtfd format which supports them much better.
The 'fix' would appear to be [without investing in Microsoft Word] to use NeoOffice or OpenOffice, both of which support embedded pictures in rtf files.
