Hauppauge a little while back posted the #3 thing (that used to require
the NDA) to their web page, no more NDA required.  So #2 and #3 are the
same thing now.

That thing is a *patch* to the kernel mainline pvrusb2 driver.  To
install it, one has to download the kernel source, apply the patch
(which applied perfectly cleanly), and rebuild.

You can look at the patch yourself:
