Having gone and looked: yeah, it does look like the OCW folks are into the OMG nobody can steal our content or else strictly-streaming model. There's not a whole lot you can do about it that I know of -- I mean, theoretically anything that you can play you can capture in some way, with a program like this (http://www.afterdawn.com/software/audio_software/audio_tools/streambox_vcr.cfm) for instance, but I've never tried and it's a little bit illegal. *shrugs*
