Hi,
Some more quick responses:
- Theater 650 Pro cards will have S-video and Composite video inputs
- you can receive both NTSC and ATSC, but there's still only one encoder so you can't watch one, while recording another using only one Theater 650 Pro
No component inputs?
But can you capture with both if one is encoding to MPEG-2 and the other just to uncompressed avi?
