Re: Poor picture quality using Satellite box in MCE

I have seen some posts which I believe were from Nigel that there is one
brand of DVB-S card that looks to MCE like it is a DVB-T card and is
therfore usable with MCE.

thanks very much JW.
Your answer is useful but discouraging in the content, as it basically
means
that MCE system is only good for OTA signals and not for
Satellite/Cable...which in the UK means 10mn people cannot really get a
decent picture out of their PC. What is the point for selling the remote
sensor with the whole pack of instruction on how to connect STB to Media
Center? Question for Microsoft, really!
One last attempt: Is there any way to use the 1394 port (Firewire) as
video
input and let the PC do all the necessary encoding, if necessary.
Also, what is the point of encoding anyway? Could the PC not simply spit
out
the signal back in its native form during live viewing and only encode
when
recording is needed (which is less time sensitive and the lower processing
power can take all the time its needs to convert?)
In fact, combining my two points above: can I use the 1394 as video input
in
pass-through mode, back to the TV (no loss of quality), and let the
encoding
start when recording/pause and other functions?
thanks for the help again...hopefully, my questions are also going to be
useful to the rest of the Satellite/Cable community (Funny enough, MCE
asks
if the input is Satellite or Cable, why so, if quality is lowered?)..

The tuner is the problem since the MCE tuner cards have inexpensive
realtime
MPEG2 endcoder chips on them and all iniputs get compressed and encoded
causing a loss in PQ since these encoder chips can in no way match the
encoder systems used by networks or DVD manufacturers which cost
thousands
of $. NVIDIA has claimed that its new inhouse designed encoder chip used
in
the new NVIDIA DualTV card is bettern than the others currently on the
market but I have seen no independend tests to confirm this yet. At least
digital TV such as that received OTA with an HDTV card does not suffer
from
this problem since the signals are already encoded by the networks.
There is no solution for MCE till Cable Cards tuners and satellite card
tuners are introduced with or after the release of Vista.

thanks Dana for your reply.
I am using brand new cables and have tried both S-video and Composite,
but
the quality is the same, i.e. very bad. Once again, if I connect the
very
same cables to the TV instead of the MCE PC, the quality I see is
almost
perfect, so I am assuming STB output and cables are fine. Which leaves
us
with the Tuner.
I have a AverMedia Hybrid TV Tuner Card, A16C (DVB-T, Pal/Secam/FM).
The graphic card is Nvidia 6600 and it has two outputs, one VGA and one
DVI.
The TV input is DVI. The image works when I use the VGA output into the
DVI
input (and the PC recognise the TV), but nothing if I use the DVI
output
into
the DVI input
Thanks for you help.

I would suspect your tuner card, or its drivers. Since you're coming
in
via
sVideo or composite from the STB, you'll probably never get as good a
signal
as in the demo videos. One thing that might help would be to use high
quality (and short) cables from the STB to the tuner.
As for the graphics card output, which card do you have, and which
version
of the drivers? Generally if you connect to the DVI output, the card
should
recognize there's a TV there and enable the signal. However, you might
be
able to enable that output from within the drivers dialog.

Hi,
I have just bought a Sony Vaio RC202 with Media Centre and I have
problems
with the video quality
The video source is a Satellite (Sky) box and I am using a Scart
output
from
the box and either S-Video or Composite into the PC tuner card. The
signal
from the Satellite is crystal clear if I connect directly STB and
TV,
but
if
I go via the PC Media Centre the output is very bad..lots of blue,
almost
like an old VHS tape.
On the other hand, when I watch some of the sample videos even in
HD,
the
quality is perfect, so I am assuming that the Video card output is
working
fine. I should however point out that for some reason I can only see
the
image on the TV if I connect VGA (PC) to DVI (TV), but nothing if I
use
the
DVI output from the Video card. Additionally, I can't get the 16:9
format,
and the video seems to show only in 3:4 (which to be honest is the
original
aspect ratio of the satellite signal).
I find it strange that, while I can import video on the PC using
1394
at
perfect quality, there are difficulties in connecting a live video
signal.
Maybe there are cards outthere with an RGB/Scart or DVI input? But I
am
not
sure this is the problem.
Can anyone help?
thanks
