simple HDTV question.

Component cabling does not support HD as well as DVI or HDMI.
Using component, you convert from digital to analog at the box, then analog to digital in the TV. DVI or HDMI keep it digital.
Using HDMI or DVI also allows the aspect ratio to change automatically - a very nice feature.

True HDMI cables all support HI/DEF. I use a Philips hdmi cable PTX-1000 series. Cheap at 42.95 Works will with my sony XBR60 LCD. Let me know if you want one or just look for them on EBAY I sell them there. Thanks

thanks everyone. that all helps very much. my tv is a pioneer pdp 5050hd, with 2 hdmi inputs and three component, s video, i link, and optical. fixed pixel or not i dunno? how can i tell? the hd box has dvi-hdtv/dish dvi(dvi-d) and hd component inputs. what would be my best connection? my dvd player will have hdmi and component, which should i use? now have an afterthought question...was it that only component cable supports progressive scan dvd? if so, which then is superior, component or hdmni/dvi? also, does dvi transmit audio like hdmi or do i use interconnects in that instance. i myhave also heard of some quite unfortunate experiences with hdmi on secretsofhometheaterhifi.com forum. any comments? thanks so much for the help....

DVI also supports prog scan, and without the d-A, then A-d conversion of lesser connections you'll be way ahead.
Go DVI at the box to HDMI at the TV. You can get cables that have DVI-HDMI connetions, or DVI-HDMI adapters. The only thing you'll miss is the sound as DVI doesn't carry audio. HDMI does.
Nice that you've got two HDMI inputs. When you get your new HD DVD player, you'll be good to go.

Hello again. You have a fixed pixel TV so I would do DVI or HDMI like the others have said and you have one of the best plasmas on the market. I will repeat however for the others who have writen that if you have a CRT HDTV direct view or projector which are still the best, HDMI and DVI are downgrades over component or RGB because the TV has to change an XY location of a pixel back to a scanned line.
