You could try a DVI extender with a HDMI to DVI adapter. It is a similar issue with the Apple TV (HDMI to SDI converter doesn't work but a DVI extender does) Am guessing it's an HDCP issue.
I do know that in Australia Foxtel actually go component out of their set top boxes because when wanting to convert to SDI, HDMI to SDI converters don't work on their set top boxes because of HDCP!!!
Also previously had a set top box that did work with HDMI out to SDI converters but was told not to update the firmware because it would break that ability. I specifically chose that set top box because I knoew it would be able to do that. That was around 2009.
The DVI extender will not include audio from the set top box HDMI but you could use a 2 RCA-3.5mm lead for the audio to attach from the set top box to the DVI extender
