Default Integrated PC/AV installation issue

Look for properties tab of your video card, there you mught find options to
change the way the card renders TV output. Be sure to be using video driver
that comes with card.

Hi folks;

Hope yall had a nice Eve and wish you the best holiday.
If Santa is welcome at your house I hope he needs a Tractor-trailer
to bring you good stuff (pretend to be sleeping then)

Now that things have settled down . . . .

One of the things I did today was to go hook up a new PC system,
integrated with the A/V stuff. Cable signal also goes to the PC and
we ran back SVHS and L/R to the TV (Mits. 35MX1). I thought the TVO
portion of the ATI All in wonder wasn't working. Switching to a
regular input worked, I used the right audio cable for the composite
video.

Now there is another issue. We could just run composite but this is
no good, the signal is slightly off standard (it is) and the Mitses
COMB filter doesn't work well with it.

Some frequency is set different, when a saturated color comes on, the
dots are stationary. You see them on alot of NTSC sets, and with one
line COMB filters the first line of a saturated block displays a
serration, or if the COMB isn't working correctly a hatch pattern
throughout the colored block or object.

However, on a "legal" NTSC signal this pattern appears to move. This
is of course because the designers of the system chose the
frequencies used so they would cause cause "interlace". On the ATI
card output, the "hanging dots" are stationary on a stationary image.
The chroma frequency must be shifted slightly, and I believe
intentionally, to simplify encoding (ATI Radeon 7500 All in Wonder w/
64MB, remote), thus making the SVHS cable necessary.

We lack the original remote to the set and can't seem to get it into
the SVHS mode. Being a tech. I think I can force it into the SVHS
mode no matter what system control says, but that is some work,
especially in this installation.

Note that as a tech I absolutely refuse to try to align the COMB
filter to this source. This would degrade all normal inputs.

Also, I wonder, will a VCR record that non-standard signal ? Probably
I think, but I wonder just how much it's degraded. Luminance will be
filtering out a
3.5???? Mhz signal, which might not bother it too much. The chroma
noise reduction scheme will probably be quite compromised though, it
might even record in black and white.

Recording VHS from this source is not the important point, image
quality is, this is way worse than it should be, and the COMB filter
is working, but when the frequency is off. . . . . I guess we need to
get it switched to the SVHS input.

Advice, comment, suggestion ?

Thanx for anything on this and thanx for even reading this.

Merry, happy, joyful
Christmas, Chanukah, Kwaanza (sorry if I spelled it wrong), Ceremony
of the Rebirth, whatever you have,I wish you a good one.
