A couple reasons..

First, every newer/modern HDTV upconverts (scandoubles/deinterlaces) the incoming signal to it's native resolution. For example; my Panasonic 42" plasma has a native resolution of 720p. Everything coming into the set gets upconverted to 1366x720. If I connect a crappy interlaced composite source, I'll get a bad 1366x720 representation of that source. Notice I said composite, not component

Normal DVD's are encoded in 480i (525i for pal?). You need to get into HD-DVD or Blu Ray before the content on the disc is encoded at any higher.

So, DVD players that upconvert (progressive scan players) are doing the scandoubling/deinterlacing of 480i content in the DVD player electronics, and then outputing it at 720p, 1080i, or 1080p (depending on your HDTV configuration). This is not always the best situation though. You need to do some visual comparisons to figure out if the the scandoubler/deinterlacer built into the HDTV is better than the scandoubler/deinterlacer built into the upconverting DVD player. If the one in your TV is better, you'll get a better picture if you output the native 480i signal and let the HDTV do the scandoubling/deinterlacing. If the one in your upconverting DVD player is better, then let it do the work and set it to output at the HDTV's native resolution.

Component is an analog RGB signal. So even at 480i (525i for pal), it's a cleaner signal than S-Video or composite.


Because not everyone can afford a HD TV, and the vast majority of monitors will hapilly run HD resolutions.
I do think its disgusting that in other contries you seem to be able to get CRT HD ready TV's for a few hundred quid whereas here in the UK even a cheap ass 21" HD from woolworths or aldi will set you back 400 pounds
I feel your pain. But for X-box/PS2 games, I would think most people would rather play them through S-Video, composite, or SCART on a 27"-36" standard definition TV (480i NTSC/525i PAL) instead of a 15"-21" LCD/CRT monitor?

One thing to keep in mind. The xbox can already output 480P and 720P, so it can already output a scandoubled/deinterlaced video signal. The X-box 360 and PS3 can output 420P (525P PAL)-31.47kHz, 720P (750P PAL)-45.00kHz, 1080i (1125i PAL)-33.75kHz, and 1080P (1125P PAL)-67.50kHz. I'm not sure what the purpose of running those systems through a scandoubler/deinterlacer would accomplish since they can already do it internally?

I guess what I'm saying is this. If your going to build a flicker fixer, dont worry about making it connect to all kinds of different systems. Make it work on the Amiga
