Thanks 'Abinadius'!
Your advice almost did the trick. After setting the ActiveX download options to 'prompt' I at least was able to select 'intall' the codec when I opened the .asf file with WMP 10, but after that I got 'error downloading codec' in the status bar. I tried repeatedly, rebooted, went back to the settings to make sure they didn't reset to 'default', thay hadn't. Still no luck Thanks for trying! Take care and happy computing
