I have KnoppMyth R5A16 installed on my Epia M1000, which has the BIOS set to display to both CRT and TV. When viewing on a CRT, all the colors look fine. However, when viewing on a TV, the colors look "posterized", with only a few colors available -- primarily blue and green. I'm using a bt878 TV card, so it's not the purple/green issue previously reported with the Hauppauge PVR 350 card. Also, my problem is with colors in general and not just when viewing recorded programs. The MythTV GUI, KnoppMyth wallpaper (Tux on the couch, watching TV), and everything else are displayed in blue/green posterized color. I tried playing around with some settings in the XF86Config-4, but the results did not improve. I've tried both composite video and S-video, but with similar results.

Interestingly enough, when I run some other distros on that same system, the TV-out colors are fine. For example, using Knoppix 3.9 Live CD, the desktop displays normal colors on the TV and monitor, with absolutely no tweaking. So, this tells me that my Epia M10000 is capable of displaying colors correctly on a TV, but there may be something about the KnoppMyth implementation/version of Knoppix that may need some tuning? Thanks for any help.

Perhaps a search of the forum?

Actually, I did search the forums and Google before posting my question. The trick is in knowing what to search for.

I had found some references to setting "DPMS" "False", but dismissed it because there was a comment that this applied only to color problems while watching Live TV and my problem was pervasive throughout MythTV. In the end, this was indeed the workaround.

The trick is understanding that you're ALWAYS watching a recording. Even when you're watching "live" TV what you're really doing is playing a "scratch" recordiing and that any type of video that you're displaying via X tends to use pretty much the same "pipeline".

Hello,

I just installed the latest release of KnoppMyth (R5B7) on a new Via M10000 Nehemiah motherboard. It is hooked up to the TV with S-Video (though Composite produces the same result). At first as soon as mythfrontend would load, the colors would turn blue/green. I rm -rf /home/mythtv/.fluxbox and after rebooting and logging in as mythtv and starting mythfrontend, the colors look fine. Now the color problem only shows up when mplayer is loaded. I could not get -vo XvMC to work under player settings, only xv would work. Anything else and mplayer would not start.

After removing /home/mythtv/.fluxbox:


Loaded mythfrontend just fine - colors ok:


This is what happens when watching video:


This is how myth looks after getting out of mplayer:


This is how X looks after getting out of mythfrontend:


Background: I have tried a few XF86Config files, including some found on Google and the XF86Config-4.epia.tvout.sample file in /etc/X11. Remember: until I removed the .fluxbox config directory it was happening as soon as Mythfrontend was loaded. Now it's only when mplayer runs.
There are no capture cards in this PC. Only the knoppmyth CD installed to HD.

Any ideas?

Have you set DPMS to False in XF86Config-4? That's exactly the same problem as all M10000 users on TV-out get when they first install. It's seen as soon as X starts. In fact you say you got it straight away, until you removed .fluxbox. Try putting that option in the relevant 'Section "Monitor"'. I also have an M10000, no capture card and I have to make that chnage every time I install KM (R5A30.2 & R5B7). Mods, can this be fixed in the next release?

I suppose a script could be written that fixes this if the Epia is detected... I await your submission.

Chuck this in /usr/local/bin/epia_sql.sh



Won't fix it for setup, but will fix it after a restart of X. Maybe echo a warning that this has occured, but I can't imagine there are many using KM with an EPIA on a monitor. This problem must affect the vast majority of EPIA users.

I love it when a plan comes together. Thank you.
