คือผมจะเอาไว้ดู DVD อย่างเดียว ส่วนพวก TV ผมไม่เน้นครับ
So you could care less about thes two functions then.
To me, progressive scan ready TV is a must for good experience in watching DVD... Pick the one that can take progressive scan signal from DVD krub.
This is my pure guess and wonder whether Khun JBC may confuse the progressive function in the TV and the one that was sent via DVD player. The later one is the so-called 'real' progressive scan krub. Forget about function in TV such as DRC progressive, DRC 100 and DRC 1250 when your DVD sent out progressive scan signal. Most of the time, these digital circuit will be 'bypassed' when you feed your TV with the progressive scan from DVD player.
Nevertheless, most TV that can take progressive scan signal usually comes with these digital circuit but not the other way round krub.
I have no time to update myself on newer models. So, from my memory, this should provide some guideline for TV that could take progressive scan signal from DVD player.
1. Sony DA, DR, HR, HZ series
2. Toshiba SZ series (not sure it's still avalable)
3. Philips Pixel Plus
4. Panny 180 series and its replacement.
#1-3 can take progressive scan signal in both PAL and NTSC system but I'm not sure about #4. To me, we need to prepare for PAL signal as you never know your DVD disc may be in PAL system. Case in point of good DVD in PAL is The Corrs Unplugged krub.
DR is the one without HDTV capability but I would try DA or HZ at minimum unless you could get DR really cheap krub (at least 30% below DA and brand new unit, not show unit).
Which one is good for you? It's you to tell me, not me to tell you krub.
Usually bigger is better for DVD watching as you will lose part of the real estate on your TV screen via the widescreen format, ie black bar on top and bottom of TV.
Try watching same unit at various dealers, see whether which picture 'style' that you

, not picture 'quality'. Major picture style, to me, include Sony which has a very crisp and saturated color while Philips is on the other side of the spectrum, soft and rather smooth - some called it 'natural'. Other brands are somewhere in the middle krub.
DO NOT judge the quality of TV on showroom floors. Just take a look its picture style. The reason is that factory preset makes TV looks good on showroom floor, ie ultra bright and ultra high color temperature for super dooper whiter than white picture to attract prospetive customer eyes. I don't think your watching area at your home looks anything

showroom, ie with ton of fluorescent light, so you shouldn't judge the picture 'quality' on showroom floir. After you bought the TV, use some calibration disc

Digital Video Essential to further fine tune it and that should be good enough. You could do more by hiring someone to adjust the 'color temperature' of your TV, ie it makes red look

red and not orange

you see on most TV on showroom floor.
Aftersales service. I couldn't stress this one less. Sony is by far the best, on average, for its aftersales service with a long history of track record. I heard complaints the most about Philips and am not sure whether it changed. You could search more for the horrible stories on Philips krub on this website.
Vertical squeeze. As far as I know, Philips Pixel Plus has an annoying white line when you do vertical squeeze. Sony was well known for this one as it does not have any for a long period of time. If you didn't buy 16:9 aspect ratio TV, then test this widescreen function on TV to see whether there is such nrritating line first. This function comes in diffrent name such as V-compression from Sony.
Lastly, I have bias in my recommendation as I personally

Sony. So, just take this one as FYI only and don't totally trust it. Then use it in a way of precaution, ie whether you could see what I said and agree with it or not. Further discussion is more than welcome krub.
Also, anybody has additional recommendation for Khun JBC, pls feel free to jump in.
