I have tried a couple of HDMI switchers in the past week.  I am hooking up a streaming blu-ray player--LG 390--and a satellite box to my projector.  I have tried different HDMI cables and I keep getting lines running through my picture.  Anyone have a similar problem and a fix?  Anyone using an HDMI switcher they are particularly please with?  By the way, the streaming BluRay player is magnificent.  I am preparing to cut off the satellite service.  Was primarily using the satellite to watch movies, or HBO (mostly boxing) and with the streaming LG I have access to Netflix, Cinema Now, VuDu, You Tube, etc.  I believe this is the future of television.  For some time I had wondered why  you couldn't just go on to your cable/satellite box and bring up any movie you wanted, pay for it and watch it.  With this streaming player you just about can.  Netflix offers a large number of movies that you can "watch instantly" and you just go to their website, set up a queue, then go to your blu ray player--for me it is connected to my projector and the movies are waiting for me to watch anytime I want.  It is great!

Is it an exceptionally long run?

 The run from the projector to the switch is about 17 feet.  The run from devices to the switcher is no longer than 6 feet.  I have tried a couple of different cables and different lengths from the devices to the switcher--no difference.

Have you tried each run individually with the switcher out of the equation?

 Oh yeah.  In fact, I have been running them without the switcher all along.  I just decided I was tired of manually changing the cable when I wanted to go from my streaming blu ray player to satellite.  The HDMI switcher at least theoretically is a great plan.  I just have to get one that works properly.  Maybe I will start working backwards--connecting the switcher at the projector and do the long cable runs to the devices.  Ah well.
