Hi all,

Just to be clear, I have eliminated the top line of snow or noise from the top of LiveTV and the viewing of recordings by way of the Myth setup screen where you adjust the X and Y overscan a bit. The thing is, that stuff up there (which I understand is the closed captioning data or something along those lines) is still in the original recorded file. Which means when I burn a show to DVD it gets sent to the image, so when the DVD is viewed it shows again. It also shows in the little preview windows that play when you browse through previously recorded shows, although this is not a big deal to me.

1-Is there a way to configure DVD transcoding to eliminate the noise?
2-I understand there are ways to remove that top line through the modeline or through nvidia-settings (although my version of the driver doesn't show overscan settings), would these methods correct the recording itself at the root? If so, does this mean closed-captioning info would be lost (my CC doesn't work, but would like it to)?

Thanks!

Here's the modeline I use:

HorizSync 31.5 - 90.0
VertRefresh 60.0 - 60.0
ModeLine "1920x1080p" 148.5 1920 2024 2072 2200 1080 1084 1094 1124 -hsync -vsync
Option "ModeValidation" "NoMaxPClkCheck, NoEdidMaxPClkCheck"
Option "dpms


R5E50
Nvidia 6200 512mb (Use DVI to DVI on LCD)
Athlon X2 4x00
1GB Ram
Westinghouse LVM-47W1 1080P LCD

Sounds like a MythTV question to me.

Sorry, is there a way to move this over there?

I am pretty sure that the noise you're referring to IS the closed captioning info, so if you crop it out you will lose the CC info.

Note that you will never see that line if you watch it on a TV set via a normal DVD player... it falls into the overscan area of a TV set. That's why you don't see it when you watch it via the TV's tuner.

Ok, that makes sense... but the thing is I typically record in 16:9, at least the things I send to DVD... so when viewed on a 4:3 set, it does show... but at least now I understand where the tradeoff would lie.

Thanks!

I don't know how nobody has been able to help you yet with this question, here is the answer...

Open up a shell window and type the following

xvattr -a XV_COLORKEY -v 0

go back to the frontend and watch TV and you'll see how those blue lines are gone.
Now when you reboot the machine you will have to input this again, I have not tried the following yet because I just discovered this yesterday but from looking at some posts, you can put this command in the xinitrc and it will do it automatically everytime you reboot the machine, the following is a quote from somebody that posted the answer on another website.

He's not talking about blue lines, he's talking about white lines at the top of the image.

If that is the case then I apologize
