You mean outside of the windows part? (only half kidding...)
test_usrp_standard_rx.cc doesn't know how to talk to the
daughterboards and tune the front end. You really want to use
usrp_rx_cfile.py.
Have you tried running usrp_fft.py and/or usrp_rx_cfile.py?
I'm not sure what throughput anybody's seen on windows. If you can't
sustain 32MB/sec across the USB, you're dead in the water for HDTV.
I strongly suggest installing a GNU/Linux distribution. That's the
platform where the primary development takes place, and where we know
(with a suitable EHCI controller) we can sustain 32MB/s across the
USB. I currrently like SuSE 10.0 and Mandriva 2006. Other have been
had success with Ubuntu and Fedora Core 4. If you go with SuSE 10.0,
spend a few bucks and get the paid-for version. It will save you a
ton of time.
At a minimum you're going to need gnuradio-core, usrp, gr-usrp and
gnuradio-examples. For fft and scope sinks you'll want gr-wxgui.
