Missing blue color for NTSC

I have just gotten to my new HD-3000. Installed the drivers and was able to get NTSC (tvtime) and ATSC (getatsc + mplayer).

However, the NTSC image has way too much green and red. As if it was missing blue component of the color. Does anyone have any idea why that could be?

Does tvtime have an old-fashioned tint control you can adjust?

Thanks a lot for the tip. I am able to get correct colors when I change the hue from 50 to 100.

Do you have any guess at why HD3000 is doing this?


P.S. Will try to upgrade to new drivers tonight or tomorrow night.


Thanks again.

Why the HD3000 made you adjust the hue? Didn't it solve the problem?

I have no idea why the hue is wrong coming from HD3000.

So I upgraded to new driver, however that did not fix the hue problem. I still had to change the hue to 100 in order to get the right picture.

Then I upgraded to 2.6.9 due to update in device mapper that I needed. Now the picture that I get looks like it is inverted. Plus the original hue problem.

I am wondering if there is some internal setting on the card that is wrong. This is very discouraging for a brand new card.

Thanks for all the help.

Can't tvtime save your hue setting?

I found the setting to save the hue, but a bit too late. Plus I beleive the card should sending correct colors in the first place. Now it image seems to be color inverted. I will try to test with another program. I really hope its not a HW issue.

Found the inverted colors problems. That option was set in tvtime. Stupid me. But I am still trying to understand where the hue problem is comming from. I tested with xawtv (just in case).

Tvtime has an invert feature. You may have turned this on inadvertantly.

On screen menu:

Setup
->Video Processing
->Input Filters
->Color invert


If the box for this feature is checked, it ix the cause of your inverted image. If this feature is not on, it is probably a driver bug. You could still use tvtime's invert feature to correct the image.

There is no such thing as "correct colors" in NTSC. That's why there's a hue control.

I wish I were joking here.
