Streaming MOV file on PC sounds muddled

[Muse]

Here's the link = 10 second movie showing Arnold Schwarzenegger. I run Windows 2000, have a fast DSL connection, a Santa Cruz sound card that otherwise seems to work fine, but it sounds muddled on my system to the point where I can't make out 80% of the words. Sounds like he's talking under water is how I'd describe it. I messed with my Quicktime 6.4 (latest version) settings, connection speed, but it remains the same. Does anybody have an idea what might be up with this?
