Using a Monoprice HDMI Splitter (PID 6192) here from my 622 to three TVs since December 2010 (all are the same model - 2008 Sony LCDs - KDL-46Z4100). No real issues with splitter. Once or twice every month or two I may need to switch splitter off and back on to get the picture/sound to one of the three TVs, but pretty rare and random. I have HBO, and I don't seem to have any HDCP issues.
