Sorry in advance for the newbie questions, but I have a couple here if
anyone feels like answering them...
On my setup with a SA 8300HD, the TV status display shows up in the
upper-right corner whenever changing video modes, like 1080i to 720p. For
all my SD programming, the display always indicates 480p, even though I know
the TV is capable of displaying 480i. Does that mean that the cable box
converts the interlaced SD signal into a progressive one? Incidentally, the
only two exceptions to this are C-SPAN 1 and C-SPAN 2, which always switch
to 480i when I go to those channels. Anyone know why this is?
Also, would DVDs played on a player with the Faroudja chip look a lot better
than a regular, progressive-scan DVD player? I've heard that the chip
upscales the DVD movie's resolution to 1080i, but how can you do that if
there's no extra resolution? Thanks,

As you know a DVD is encoded at 480i in a compressed digital format.
Often the best approach is to use a video output to pass this digital 480i
data into a digital TV where all the processing will take place in the
digital format. If the set displays at a native 480p or 720p or 780p or
1080i or even a 1080p the set will do everything.
If you have an older digital TV or a set with inferior digital chipsets
then you might benefit if the player itself does the conversion. But you are
correct, the conversion will not create any additional resolution; but it
still might look better on a particular display while viewing a particular
source program.

I believe you can change your setup for the 8300HD so that it sends the
video to your TV all in a particular chosen mode or as the signals come down
off the cable. Some who post here will know exactly how you can make that
change, if you want to.
My 8300HD came from Time-Warner pre-set to send everything, HD and SD, to my
TV at 1080i, which the Sony HDTV must like just fine, as the HD pictures are
stunning and the SD almost as good, if not as good, as I got via a
CableCard, with the TV doing the upconverting. So, I have just left it
alone.

Many if not most hdtv's convert 480i to 480p without you doing
anything...it eliminates the scan lines and usually makes things look
better. But the bit about C-span makes no sense at all. Cable box or
TV, I can't think of any reason why ANY 480i source would be treated as
an exception.

Okay, but why is the Faroudja chip so highly touted among HD and AV
enthusiasts? The way it's talked about seems to indicate that it makes some
big performance difference. Actually, I have the Shawshank Redemption on
DVD, and there's a lot of noticeable artifacting (I think that's what it's
called, those blocky pixels when you get closer to the TV) when it's played
on my progressive scan player, especially compared to when the movie is
aired on Showtime HD, where it looks much better. I wonder if a player with
the Faroudja chip would address that kind of problem. Oh well, I guess it
won't matter in another year or so when the movie libraries are ported over
to whatever becomes the next movie disc format.

It's really interesting actually, because there's a menu on the 8300HD where
you can select up to the four outputs that it supports: 480i, 480p, 720p,
and 1080i. I was fooling around with this a little bit and found that if,
for example, you only set 1080i or 720p, all channels, whether in SD or 720p
or 1080i, will be scaled to the single resolution that was selected in the
menu. I tried selecting 720p, 1080i, and 480i, but not 480p, and found that
it automatically scaled SD shows to 720p; likewise, if all four resolutions
are selected, the TV will switch resolutions each time. Even more
mind-boggling is that my set (like most LCDs) only natively supports up to
720p, so it's always converting to that, and then to the 768 lines or
whatever the LCD's resolution actually is. Lots of conversions going on all
the time.

Believe me, I'm pretty confounded by the C-span thing. Could someone try
turning to C-span on an HD set and say what resolution the TV outputs it in?
Maybe it has something to do with it being a live unedited feed.
