Had a D* tech install a HR34 two days ago. I'm having pretty bad video/sound lag and pixellation problems with that unit. I also have HR21/700 and HR23/700 that have been here for a while. No problems with those receivers. He installed a SWiM 16. There is a line running from the 1-8 outlet through a 2-way splitter to the HR 21 and HR 23. The cable to the HR34 is from 9-16 and the 29vdc power supply is also connected to that cable in-line behind my HR34. Could that be causing the problem? I've heard that the 29vdc needs to be on an independent coax connected to the power outlet independently. He originally tried that, but had problems getting the only other free cable in my house to tone out. Thanks in advance. Also, I'm a total newbie and not familiar with much of the lingo here, so go easy on me.
