When using VS Replay, we've seen some initial issues getting an HDMI video feed from Sony HDR CX camcorders. These are typically used as low cost cameras on endzone rigs for football.
Here's how to fix...
1) After you plug in the HDMI, press the play button on the left of the screen...then press it again so its back in record mode
2) This should unstick the camcorder feed and be visible in VS Replay
*NOTE - you may need to do this every time you start the system up for a new game
