TV Out problems
 
Arrgghhhh..... Last two days I have been trying to get the TV-Out to work correctly.

After reading all the documentation on Linux support for NVidia cards with TV-Out, I bought GeForce4 MX 440-SE based card. Installing the card and the drivers was easy... But when it comes to using TV-Out that is whole different story....

First of all, I can see the signal on the TV, but the quality is absolutely unacceptable! There are wide lines that roll vertically constantly. I played with all the settings in XF86Config file, but nothing has improved the situation.

Has anyone seen this before? Is this the quality of Linux support NVidia has for TV-Out?

:mad: I am sooooo frustrated, I am ready trash NVidia card and get myself a good old SVGA-to-NTSC converter (or even an RF Modulator)....

Same problem here. I'm wondering what kind of TV (make+model) you're using. I've come across some peripetic info. on my TV model that might indicate that it has some sync problems w/ S-Video so if we have the same make/model, maybe both our probs. are TV-related, not card related?

I think I found the root cause of the problem: it is the motherboard (on-board video chipset)!

When I pull the card out of my linux box and tested in my XP, everything seem to be working fine. So, I assumed that the problem was due to the video card/driver/configuration. After countless hours of fiddling with the card settings, yesterday afternoon I gave up and bought myself AverKey iMicro (external VGA to TV) unit. To my surprise, I saw the same behavior with the external converter as well. At that point, I realized that the problem is with the motherboard!

Now, I plan to get myself a new motherboard...

-SiS730S chipset
-AMD Athlon XP/Athlon processor up to 200MHz FSB

I disagree with your assesment, I just think that XP is being smarter in selecting the proper timings for the video signal. Err...guess I'll do some Modeline reading. Let me know if your new motherboard works. (BTW, I'm using a Chaintech mATX.)
