All new models released after 1 Jan 2011 are not allowed to do HD over component. In practice, many 2011 models don't do component at all. It looks like some if not many pre-2011 models had HD over component disabled in software too for no good reason. Many of those pre-2011 BD players that did do HD over component are now being served firmware updates that disable HD over component (they like you to buy new TVs). Finally, if you manage to find one that does do HD over component, new discs released after 1 Jan 2012 may have an ICT flag which means all BD players will disable HD over component no matter what.
There are a couple of options for HDCP-enabled HDMI to component via converters; the ViewHD and the HDFury3. The ViewHD has a flaw which means it supports 1080p without an option to disable, which means some Blu-ray players, allegedly those from Samsung and LG, will force 1080p, which just won't work on a HD CRT TV - you would need a BD player that allows you to force 1080i. I think Panasonic BD players can do that? The HDFury3 is a more expensive converter but allows 1080p to be disabled.
There are multiple revisions of the ViewHD on Amazon. The older ones should not be bought.http://www.avsforum.com/avs-vb/showthread.php?t=1361422
If I get a blue-ray player and blue-ray disk,will it display at 1080i or be down-converted . The connection has to be through the sets component inputs. Thanks for any info.
I need to ask, why does it need to be though component? Your model of TV has a DVI input with HDCP support; DVI is just HDMI without sound, and you can convert from HDMI to DVI with a cheap mechanical converter.
