I feel for you. I'm in the same boat. Since installing Tiger 10.4.2, I can no longer use WMP. I've uninstalled it and downloaded and tried to reinstall on several occassions all to no avail. I've also tried VLC but that doesn't really do the trick either... some .wvm files play and others don't.
Does anyone know of another bit of software that will play .wmv files on a Mac running Tiger 10.4.2? I would gladly pay for the program if it works.
