My name is Felix Kolotinsky and I am FAE at AVerMedia Technologies, Inc USA office.
AVerMedia has a product AVerTVHDDVR that works with Flash Media Live Encoder 3.1, AVerTVHDDVR is capable to capture HD quality up to 1080i from build intHDMI, Component YPbPr and Analog from S-Video and Composite.

Below is screenshot that I took from FMLE using AVerTVHDDVR, my source was HDMI from Direct TV Set top box, in this case I was encoding in 1080i source into 720x480, you can Encode up to 1080i, however this requires Quad Core CPU
I recorded an instructional video and posted on www.youtube.com, here is link to it: http://www.youtube.com/watch?v=AMF-jkZxeMk
