I’m having the same issue with Ultrastudio 3D’s presets. I’ve got an Xbox 360 set up to run at 1080i60, but using the matching preset shows nothing but black (and no audio) in Media Express, Premiere Pro CS5.5 and Final Cut Pro 7.
I have the same 720p-only issue with iPad 2 capture, and audio is not captured when mirroring its output. However, it is captured from an iPhone 4 over HDMI when playing unprotected video content.
I really need 1080p output; although it would still be framed with black and not necessarily 1:1 representation of pixels on the iPad’s built-in display, having to upscale the frame by around 150% for full-screen playback on iPad 2 isn’t acceptable.
Prior to spotting your post here, I contacted Blackmagic by email. It was the support team that suggested trying an Xbox 360. Since then I’ve replied directly to the emails (on Thursday and Friday evenings, UK time) and had no response.
Right now I’m dismayed by the quality of the software, which prevents me capturing anything like the quality from consoles and other consumer HDMI-equipped hardware that Blackmagic’s detailed specs say is possible.
