I second this request.
We use 2 other slingboxes at my work to record scheduled audio events in another part of our campus. I bought one of the new SB 500's thinking we would be able to do something the same with video, using an HDMI input from a camera, but now the SlingPlayer doesn't work.
Unfortunately, our campus' bandwidth isn't able to handle sending HD video and audio off campus and then turn around and bring it right back on campus, and there's too much of a delay compared to using just the SlingPlayer.
Please just let the SB 350's and 500's use the software like the HD and Solo...
