Just wanted to report that I'm successfully capturing/recording from two of these units via firewire. Using win7 32bit / xp 32bit, CapDVHS and the firestb drivers floating around on the net. It won't work with any 64bit os. No drivers available yet that I know of. Make sure you roll your win7 IEEE 1394 driver back to the legacy driver BEFORE you connect your stb to your PC, or else you will have to reboot everything before it will work. Other than that, really no tricks. Been working without a single hiccup for a few months now.
Lastly, I've been reading a lot of people saying you can't pass digital audio over a DVI to HDMI cable. This is false. I am doing it as I type. All that's required is an audio capable video card, and an HDTV with HDMI ports to connect to.
