My name is Khang Nguyen and I am FAE at AVerMedia Technologies, Inc USA office.
AVerMedia has a new product AVerTV Express HD DVR for an expressCard slot that works with Flash Media Live Encoder 3.1, AVerTV Express HD DVR is capable to capture HD quality up to 1080i using component input.
Below is screenshot that I took from FMLE using AVerTV Express HD DVR. My source was component from a DirecTV Set Top Box. In this case I was encoding in 1080i source into 720x480. You can also encode up to 1080i, however this requires Quad Core CPU.
If you are interested, here is a link to the product description http://www.avermedia-usa.com//AVerTV/Product/ProductDetail.aspx?Id=490

Enjoy,
Khang Nguyen
