Disclaimer: I'm not using the USRP on Windows, just lending a hand in
porting the code. Among the lurker on the list, are there any
Windows gurus who can help better, starting with, for example,
beta-testing the Windows Installer Martin kindly released?
Rem: no need to own an USRP to try out GNU Radio on Windows.

Perhaps not enough buffering? Having source/sink in threads helps sometimes.
Martin will have better insight on the topic.
