We recently got the HR34, and recently noticed these diagonal "lines", if you will, through the screen. It's not all the time....only certain scenes/lighting/colors. It looks sort of like when you see the screen refresh on a computer monitor in a video. That's the best way I can describe it. So, as a process of elimination, to rule out the TV, I tried my HR24 in the same spot, and couldn't get it to do it, so that points to the HR34. Then, I tried HDMI, and it won't do it. I have an older TV that has one HDMI input, and we use that for the DVD player, as it doesn't look very good via component, and the HR34(or 24) looks fine with component. Now, it obviously shouldn't be getting these lines, as the HR24 doesn't at all, and the HR34 doesn't with HDMI, so I can have DirecTV swap it out, or get a good quality HDMI switch for now.....but I figured I'd ask here, to see if anyone else gets this, or if maybe it's software related, or anything of that nature.....possibly. As always....thanks in advance!
