    As noted above, I did buy a different HDMI 3-way unit, the Stellar Labs 3x1 HDMI Switch, MCM # 33-12720, to try in the place of this one. The Stellar Labs switch did fix the annoying problem that this unit had with the audio sometimes not switching on with the video. However, both switches cause the Roku LT that is in the A/V system to shut off its RCA jack A/V outputs, even though with a direct HDMI connection to the television the Roku A/V outputs stay active. Aside from that minor problem, which is due to the Roku firmware, the Stellar Labs switch works perfectly and I recommend it over this one.

    When this device is used with some HDMI devices, odd things happen. I have a Rocu LT that I simutaneously use the A/V jacks to record on a separate DVR while watching TV via the HDMI port. It all worked fine until I added this HDMI switch in the path to the TV. Surprise! When connected to any of the HDMI input ports on this switch, the Rocu disables its A/V ports. This only happens with the HDMI auto selector switch is in series, not when the Roku is connected directly to the TV. The second odd behavior is that when this selector switch automatically (and correctly) switches to a HDMI source that has just been turned on, sometimes the sound doesn't connect. I discovered, after a lot of trial-and-error, that the cure for this problem is to power up a second HDMI device connected to the switch, wait for it to connect and the HDMI selector to find and switch to it, then turn the second device off again, at which time the HDMI selector finds the first source again and this time the sound also connects as it should. This is obviously a pain to deal with on a regular basis and also totally mystifying the first time it happens. DISCLAIMER: These shortcomings could be HDMI protocol problems, in which case the real solution is a RC operated switch. I may buy and try another brand of auto HDMI source selector, in which case I will report the results here.

    OK but short on instructions.

    The device works, but it came with NO instructions/information. It has a micro USB connector on one edge with the word "POWER" nearby on the top with an LED. You can just make out the LED in the catalog photo. I tried connecting a USB charger to it with no results. I'm not sure what that connector is for.
