When I download certain .WMV files, and try them in either Mplayer (latest version) or VLC (latest version), only the audio plays - no video. Anyone any ideas? I've got WMP 9.0, which I've uninstalled/reinstalled about 5 times, but when I double click it, the icon bounces up and down in the dock for about 2 mins not doing anything, then finally stops bouncing (still not doing anything), and I have to force a quit because it's "not responding". FYI: 1.8ghz G5 w/1.5GB RAM/10.3.4. Can anyone help?
