dvi vs. component

This is an excellent question; I also would be interested in others experiences. I'm considering getting a DVI DVD player for my HD ProJo and had the same component vs. DVI questions. From my understanding, the DVI allows a 720p picture from compatiable DVD players which should produce a much better picture than the 480p standard. However, none of the employees I've talked to at various stores, including the BB where I'm working this summer, have had any imput. Guess, I'll do my own research and post my findings here.
 
Current DVDs don't carry resolutions higher than 480p. Any player that advertises 720p is lying.

As far as DVI goes, I can't imagine that there would be any noticable difference compared to regular component.
 
DVI can only help if the equipment at each end uses it properly. There was a similar complaint years before with equipment that had component output but badly implement circuitry driving it so that most of the advantage was lost.
 
I suggest going to a real audio store, not BB or
CC. When I lived in CT, I would shop at www.theaudiostore.com. They dont sell sony at any of these places, but their knowledge is off the chart. They will tell you the difference, and the pros and cons.
 
DVI is a pure digital signal, while component takes the digital signal of the source, breaks it down to analog, then it is brought back up to digtal in the TV. Component sees more degredation in the signal quality because of the digital > analog > digital change.

Like epobirs said, the quality of your DVI signal relies completely on what you have on each end of the cable. DVI is too new for most players to use it properly.
 
I have one video source with DVI output (my Pace cable box) but I use component video cables instead. Although my cable box supports high definition signals, it will only output HD via the component video cables and restricts the DVI output (for copy protection?) to 480p. Maybe your video source does the same thing.
 
I'm thinking it does. I took the cable back today. I guess I'll have to keep switching out my systems if I want to play through component. Only 2 component video in's. 1 for cable and 1 for a system. I really need someone to make a decent device to let me hook all three up and send one to the t.v.
 
I use the pelican pro system selector and I've never had a problem with it despite the reputation of pelican products. I also have a component switch box from JVC which was far more expensive but had less signal loss. The pelican box also includes optical audio out and a hub for connecting your online connection and then out to three systems . The pelican was 100 bucks and here it is www.pelicanacc.com (go to universal section) and the JVC one I got at www.svideo.com Both of these work great with all three systems
 
Key Features


Progressive-scan DVD player with DVI digital output and upconversion of DVD signals to 1080i/720p

So does this mean the dvd player is still 480p but upconverts t through the dvi digital output to make it 1080i/720p?


if it does then it should be a better picture shouldnt it.
 
Its converting the signal, however you wont see any picture improvements unless the original source is ment to run at that quality.

For example you could use your Gamecube GBA Player to play a regular monochrome gameboy game. And have the gamecube connect through a component source, but the quality of the gameboy picture will not really be upgraded.

Yes, it will upconvert it. I'm not sure if the picture will be better, but I've read comments from people that generally like the results. I think the big advantage is when you're running it through a projector, and you don't have a line-doubler. This would be a decent alternative to using a line-doubler or a home theater PC.
