Recording QT Subscription Stream (lynda.com and apex.vtc.com)

Hi,
I've tried out a lot of the stream recorder programmes and they work great with everything except the one thing I want them too! I recently bought a month's subscription to an online tutorial site, www.lynda.com and am also looking at getting one from http://apex.vtc.com . However I can't seem to record any of the streams, even if they or a link of sorts does show up in say, URL Snooper or MovRecorder. They are in QuickTime format.
I was wondering would someone know why this is? Can they be recorded or will I just have to watch what I want to in the first month and hope it all sticks!?

Thanks in advance,
