If you have a digital TV like a DLP or LCD, then using a DVI or HDMI and an
up-converting DVD player will keep the video always in a digital format and
will not have to convert to analog and then back to digital in the TV set.
This will probably give some improvements, but you would have to decide if
it is worth doing. I do not have an upconverting DVD player.
HOWEVER using a fast computer and Zoom player with FFDshow software can
result in very noticeable improvements. Check here www.avsforum.com under
the HTPC for more info. I use a P4 3GHz and upconvert DVD files or disks to
HDTV resolution and then do 3D noise reduction and image enhancement all in
real time in software with a DVI digital connection to my 50 inch DLP set,
audio is SPDIF digital to my amp. I have compared identical DVD files
played on my 3 DVD players and played on the computer and the picture is
much better played on the computer. The most noticeable is the MISSING mpeg
grundge and mosquito noise that is present in all my stand alone DVD
players, none do up-conversion so I use a component output to the DLP.
I watch HDTV movies from my big dish and I can say that the computer
conversion looks very close to the HDTV movies, just not quite as sharp as
the real thing.
I have designed video stuff for 40 years and I thought that this kind of
"fooling around" with the video would not make it any better, but I was
wrong, it is well worth the trouble if you are a movie buff and want the
best picture possible.
