I'm just getting my mythbox working, and I go to an HDTV channel and it displays as if the content is 4:3, i.e. it's stretching it so there's letterbox on the video. If I watch the show directly from the cable box it formats it correctly, 16:9. The mythtv interface displays correctly at 16:9.

When I force the aspect ratio to display at 4:3 it seems like it looks correct. Is this a problem or just a quirk?

And how would I correct this problem with DVDs? I don't know if the default player for DVDs is mplayer, but it is for my install. How would I change that?

Thanks for the help.

I'm not actually running Knoppmyth, but this doesn't seem like a FC4 issue, it seems like mythtv.

System Specs:
Athlon64 3000+
nForce4 motherboard
geForce 6600
Sound Blaster Audigy
Motorola 6200 STB via Firewire
Fedora Core 4
MythTV 0.18.1

if you'd like to know anything more, I'll gladly post it. If anybody wants to see my xorg.conf file I can put that up as well.

It isn't a MythTV issue, it is an issue for whatever you are using to playback the DVD. If you are using MPlayer, you need to add "-monitoraspect 16:9" to the line that configuration settings.

When the source is open, the possibilities are endless!

And if you're using xine to play DVDs, you need to modify your XF86Config file and add a DisplaySize line that is in the proper 16:9 ratio:

As for your HDTV displaying incorrectly, what modeline are you using? Is it 16:9 or 4:3?

thanks, worked perfectly



how do I check my modeline? and how do I change it?

You set the resolution that your system uses by creating a modeline and setting XFree86 or X.org to use that modeline. Most distros include modelines that work with monitors. They usually include standard 4:3 modelines like 1024x768 or 1600x1200. You may have to add or uncomment modelines that give you 16:9 aspect ratios.

With KnoppMyth the doc you'd change is at /etc/X11/XF86Config-4. No idea what FC4 or X.org uses; I'd advise reading up on how to change resolutions with FC4. This is pretty standard stuff and you should be able to find a number of HOWTOs.
