NEZBO, first you should have used us! That cable box probably uses the 9300 series HDMI chipset from Silicon Image. If they used that chipset, it is known to create a clock stretching issue which will result in either an intermittent picture or no picture at all. By placing a cheap splitter between the source and the TX side of the HDBT pair, it reclocks the signal correcting the problem and all is well. This fixes 99% of these types of issues.

To address this and other requests, we will be shipping a new version of the SoloCAT HD series called the SoloCAT HD Ultra. It will have a 1X2 splitter chip designed into the the transmit side which will mirror the HDBT, along with audio return path (ARP). This new TX/RX pair will have HDMI over HDBT, bi dir RS232, our proprietary IR circuitry that will work with just about any IR blasters and receivers, 4 ports of 10/100 Ethernet and audio return path along with our power over cable design. Available at the end of March.

That's it.
