2 issues with the 2006 AIW PCIE card

1) When I open the TV in multimedia center, it displays the TV for
about a second and then it dissapears (the sound doesn't dissapear),
however, if I capture video in Ulead Videostudio, it displays the TV
input.

2) The ouptut on a TV through a 25 foot S-video cable displays 3 or 4
scrolling bars continously. I thought the S-cable was defective, but
there is no problem when I send the output from a laptop through the
S-cable to the TV.
 
Problem #2 sounds like a ground loop or hum pickup in the cable.
Basically, a ground problem between the equipment involved. The laptop
is isolated from the AC power line and the utility ground, but the
desktop is not. This could be hard to fix, but it's not really a video
card problem, rather more of a cabling and grounding problem. [plugging
the TV and computer into the same wall outlet might help, but might be
physically impractical]

The laptop is connected to an outlet also.
Could it be a power supply problem with the desktop?

To be more specific about what happens: The TV displays everything,
but there are some areas (what I called "bars" earlier) which are
lighter in color from the rest of the TV display. These lighter areas
scroll up and continously.
 
Your description sounds exactly like a hum or ground loop problem, and
no, it's not likely to be a power supply problem or, really, any problem
WITHIN the computer. Nor, really, is it likely to be caused by the ATI
card. Try plugging the TV and the computer into the SAME electrical
outlet; try running a separate ground wire between the TV chassis and
the computer chassis.

They are both connected to the same power strip and the problem still
exists.

1 sounds like a bad install of MMC. First thing to do would be a Repair
install of MMC. AFAIK Ulead would only require the card drivers be installed
correctly.

2 Have you tried making adjustments in the cards TV output? Is this NTSC or
PAL?

It looks like the problem was the TV. I bought another TV and the
problem has dissapeared.

The new TV has HDMI and S-video inputs. For some reason, the TV
display looks better when coming through the S-Video than through the
HDMI. I would think that it would be the other way around. Any ideas
why?
 
HDMI is digital, S-Video is analog. HDMI should look a lot better, but
three conditions to that are that the video card and the TV are
operating at the same resolution, that this resolution is the native
resolution of the TV display, and that the TV isn't doing any gross
conversions of the input signal (it's unbelievable what some of the TVs
are doing ... basically, in some of them, there is always a scaling
conversion no matter what you do).
 
How do I find out the native resolution of the TV? The manual says
that it supports 480P60, 720P60 and 1080i60; whenever I select the HDMI
input in the TV it displays "720P60" on the screen (where does the ATI
card control this?)

If the TV is set to 720P60, what is the equivalent screen size in
Pixels? I have it set at 1024X768 at the moment.


The TV allows me to turn on or off something called "Scanning Velocity
Modulation" , what effect does it have on the TV?

I don't have any experience with HDMI but if the resolution is higher analog
TV will usually look worse. I wouldn't use more than 800X600 on an analog
TV. 1024X768 on my 15" LCD monitor looks a little jaggy. On my 19" LCD
1280X1024 it's usually kept in a Window. PQ varies somewhat by what channel
is tuned in even on cable.
