cannot get windows media player to open and work on my iBook G3

Do you have at least quicktime 7.1 installed? That's required for sure.

If yes, it may be that you need a G4 to run, not positive on that 2nd bit though.

The error, does it correspond to WMP or Flip4Mac? If you're still trying to install or get WMP to work, don't, Flip4Mac works just fine with little hassle.

Flip4Mac does not work on a PowerPC G3 processor. Try getting the Windows Media Player by Microsoft. I believe that one will work. Though I don't know what kind of media playing performance you will get of a processor without AltiVec (not a G4/5).

Edit: wait, apparently "older" Flip4Mac might work on G3 too.
Edit2: Flip4Mac v2.1.3.10 should work. v2.2.1.11 too

Why don't you try VLC? It opens wmv-files.

I think for in-browser stuff you need the flip4mac plugin to get the videos to launch.

There is a VLC brower plugin for os x, its quite old 0.8.3 or so.
