Just got my HDTV yesterday and I noticed some major jaggies when watching dvds via the component jacks. It was a standard definition dvd player and the tv was set to upscale both to 1080i and then 580p - both pictures were jaggified. would HDMI upscaling players solve that or is that the nature of non hd/blu-ray dvd players?

This is on a CRT based RPTV (Hitachi).

still had jaggies. I turned off all video "features" as well, which helped but you should still see jaggies in slow moving scenes when the camera stays on frodo's face, for example).

Your best bet is to replace your DVD player. Jaggies are usually caused by poor deinterlacing (link). I have a Panasonic CP72 changer with a Faroudja deinterlacer. I send a 480p signal to my plasma and the picture quality is outstanding. If I were buying a DVD player today, I'd go with one that featured HD upscaling.

While I'm sure there are plenty of knowledgable people here at ATOT on this matter, I'd recommend posting this over at the Audio Video Science Forum.

I have an account there and as far as Home Theater 'Geekness' goes, you'll find no better site on the Internet... Period!

I'll bet they can answer your question spot on and in fact I'll bet dollars to doughnuts that the issue has already been raised there several times and a quick search may be all you'll need to get to the bottom of your problem.

I noticed the same thing on my projector when setting my DVD player to progressive scan mode. It seems like the PJ was performing it's own upscaling on and already upscaled image from the DVD player and somehow the sync was getting off a bit. Or something like that :confused:.. At any rate the bottom like was sync issues between my DVD player and my projector...

My solution was to replace the DVD player YMMV.

The simple answer is to make sure your DVD player is set to output widescreen at 480p.

Most people, when they get their first HDTV, leave the DVD player in its default modes. This means you're sending a low rez picture and your TV has to stretch the picture to make it widescreen. Change those settings and your pic should improve a ton.

hometheater pc FTW!

I run Theatertek 2 and apply FFDShow Filters.
My settings for FFDShow are resized so my 720x480 picture gets converted to 1280x720 than I apply Lancoz 4 and some sharpening to it prior to it being sent via HDMI over to my DLP.
You'd be surprised what a HTPC can do compared to an expensive dvd player. Much more you can do. Nothing like browsing the web on an HDTV or playing HL2, Prey, COD2 etc.. on a 50" DLP
Pretty fun.

If you stick with set top boxes make sure you do change the basic settings for your dvd player which has been already mentioned.

Try a different means of connecting also but I guess if it's just a standard DVD player it probably doesn't have anything better.

What make and model of player is it? What TV model do you have? Just saying "My DVD player and my TV look jaggie." will get you killed over at AVS. Have you tried other disks? Some DVDs are poorly authored. There's not enough info in your post to be able to begin making suggestions.
