Motion blur
I'm having a problem with my extender setup. What I thought was a stutter, seems to be more like a "motion blur" to me now. I notice this when watching HD-PVR material on my HD200. Funny thing is, I have a samsung DLP and I thought DLP's didn't suffer from motion blur. I have the HD200 locked at 1080i connected via HDMI to a Sony DG-920 AVR. Anyone care to take a stab at it?

You might see if you experience the same "motion blur" at 720p.
720p is going to be better for anything "motiony" random google hit on the subject: http://ezinearticles.com/?Eye-Candy?...80p?&id=123148 |

I may go to 720p, but you think it'll sacrifice PQ with the HD-PVR?

All HD braodcast are 720p or lower. There are a lot of advantages setting your STB to output 720p. You will not loose any picture quality since the STB will have to upscale if you have it output anything higher then 720p. Sage HD will do the Upscaling for you. |

SageGk- Have you tried setting your HD200 to do native resolution switching, so it will switch to the resolution of the current video file? I have absolutely no idea if that would help. I'm just saying that because I would think (perhaps incorrectly) that most nice TVs would have better upscalers than the extenders. |

I hate native switching because it takes quite a few seconds to change resolutions when changing channels. I'm going to lock the box at 720 and see what happens.

If by "higher" you mean "of better quality" I think the debate is still ongoing. Google "720p versus 1080i" and you can join the conversation on any number of forums. The main argument seems to me to boil down to some saying that 1080i would more properly be called 540i which would make a major impact to public perception. It's probably just a matter of personal preference. For myself, I can only describe 720p images as feeling more "solid" for lack of a better word -- less jittery or flickery maybe.
I do physics for a living, so I'm actually more engaged by a bit of research done by the BBC which suggests that for my particular viewing situation, my eye can't appreciate resolutions beyond 1280x720. If you're a science or engineering guy, this is interesting... http://downloads.bbc.co.uk/rd/pubs/w...les/WHP092.pdf On an anecdotal note, I recently had a DirecTV installer come to hook up a new HD receiver (DirecTV can't imagine a world where the customer could do this themselves??). The installer related that in the "thousands" of boxes he had hooked up, I was the first person to ask that he set the resolution to 720p. He just shook his head and grinned and said "oh yeah man,... you know it". Last edited by ChuckSchick; 03-02-2009 at 12:38 PM. |

I have a friend who works at a local science museum in their IMAX dome theatre. They had been looking into moving from their current off-brand IMAX projector to a digital projector. They got a demonstration done and have determined that digital projection just isn't there yet for the size of screen they have. I believe they were using 2K resolution which is higher quality than 1080p and you could see pixels in the video. And I think even 4K resolution wouldn't be enough with their screen size. Granted, most people aren't going to need even 2K resolution. But when you start talking about people with their own projection media rooms with screens well above 62" 1080p isn't really even enough.

720P has a higher data rate than 1080I, so yes it is higher resolution in that respect.

Is there any truth to the 1035i claim, or is it just anti-interlacing FUD? In my case, my Samsung 630 set takes about a second to switch between resolutions, so I turned native resolution switching on. My TV seems to be a little better at upconverting than my HD100 (and I record HD via firewire and QAM, so I don't/can't use the HD receiver to upconvert). |

It appears that 1035i was the format used by the Japanese analog HD video standard.

Unfortunately, everyone on this board will probably be papering their theater room with video wallpaper in a decade or so. Then I'll be really lamenting the fact that I've downconverted all of my blu-ray rips to 720p! Oh well, I'll have a robot butler by then that I can get to re-rip all of my discs. Alternately, given the current state of the economy, Instead of home theater for a hobby, I might be hot-gluing spikes on football pads for my next trip into the thunderdome. Anyhow, how is the motion blur problem coming? |

I locked the box at 720p and no more blur/stutter. I'm not sure if I'm seeing grainy-ness on my 56" DLP or if it is in the broadcast but I'm leaving it at 720p for now.
