HDTVs aren't always better than CRT. Some have these flaws. Heck, I've heard some HDTVs aren't good for rythym games because of the small lag between image and sound.

Yeah, its related to your screens response time. If you hook up a HD console to it you will see the same problem. My LCD screen has a 2ms response time and none of my systems lag. Most people feel comfortable with 4ms but it is felt anything higher and you will get lag.

I use component cable on my LG LF15 32" and it still looking great, actually better than my CRT TV.

Oh, and don't forget to adjust in Option to let your Wii know that you using HDTV too.

maybe you can post what ,model tv you have so we could see the specs, mainly the response time if you are having lag

lol @ HDTV causing "bad framerate"

Component cables can generally be had for not much money and quality seems to be much the same regardless of brand. I have the Nintendo ones and a cheap third party alternative and haven't noticed much of a difference.

It wouldn't make sense to me that you'd have ghosting only with Wii games as that should be a function of your TV and to my knowledge shouldn't be impacted greatly by the cables you use.

My advice would be to buy some cheap cables or borrow some if you can to see if it makes a significant difference but as LordTheNightKnight said a 480i/p image is not necessarily going to look better on an LCD than a CRT.

Get the wii oficial component cable.

O cabo por componentes deve resolver o teu problema, vais notar uma melhoria enorme na imagem, do dia para a noite.Deve haver um menu com uma opção hdtv, 480 p ou progressive scan . Qualquer loja de jogos tem o cabo oficial à venda. Também podes optar por comprar um cabo com 3 ligações, uma para cada consola wii, ps3 e 360, caso tenhas ou penses vir a ter mais consolas. Este cabo triplo também deve dar para a ps2, pois o cabo de componentes da ps2 e ps3 é igualzinho. De qualquer maneira se adquiriste uma hdtv, esta é a melhor coisa que podias ter feito, agora só falta ligares o pc à mesma.

my Wii is hooked up to an HDTV and it looks fine, and I dident notice point lag, im using a Sony Bravia

I specifically looked into picture lag when purchasing a flatscreen TV. I would guess that many low-end LCD's may have significant lag. Some TV's provide a 'game' option to remove picture processing. You might be out of luck with your TV. The Panasonic plasma I ended up getting is terrific. Wii looks great on it, and no noticable lag.

Ghosting and input lag are due to the TV, not the game console.

For a quick check, If you have any other consoles, plug them in and see if they get ghosting, if they do that means your TV has a long response time (essentialy how long it takes for a pixel to change) High response times cause ghosting. Most HDTV's with high response times have a "game mode" to reduce it, I suggest looking in your manual or settings to see if your TV has game mode, it helps a ton.

The component cables, and setting the Wii to 480P, should remove all bluriness and make the image sharper, get the official Nintendo ones, they are cheap.
