Mac computers and HDCP

[Downtown]

Anyone have problems with Macbooks giving HDCP errors when outputting from a Mac to a capture card? I installed a rig at a club with an AVerMedia DarkStar HD capture card. Worked fine for the PC DJ, hooked it up to a nice HDMI splitter, but when we get the MacBook DJ's video input (They use Serato to VJ) it gives me HDCP errors. The only 2 supported outputs from the MacBook are 720p and 1080i. Any advice?

Is it possible the Mac DJ used DHCP content when the other DJ didn’t?

Some HDMI splitters will allow you to bypass DHCP (I’ve got a drawer full of them) but not all.

HDCP stripper
Cheap chineese HDMI splitter, where in 1st output is connected HDCP compatible device like TV.
EDID Emulator (i used kramer DVI) - so your macbook detects Kramer, not Aver and sends clean output signal.
