[Openchrome-users] Mode settings for PAL 16:9

[Evan Roth]

Hi Folks,

thanks to your drivers, i've finally got xine to use the via hardware 
decoding on my epia sp board (taking cpu from 55% to 7% usage).

The one big issue i have left, is that i can't seem to get X to go to a 
nice mode for my tv.  i've been following the guide by Terry Barnaby at 
http://www.kingcot.eclipse.co.uk/unichrome/unichromeTvOut.html...but i'm 
just not having any luck.

My hardware:
VIA Epia SP13000 (with the CN400)
TV is a Sony Vega 16:9 PAL

The best I can do is use "720x576", which does not use the full screen 
and is somewhat centered (meaning there is a bit more border on the top 
and left).  When i use Terry's tvout test from 
http://www.kingcot.eclipse.co.uk/unichrome/tvoutTest.html, I get clumped 
lines, indicating (according to his details there) some sort of scaling 
or filtering.
If I read his paper correctly, it seems like 720x576Noscale is the way 
to go, but that is all garbled on my tv.  I'm able to make out the to 
blueish window bars in the basic X windows manager, as well as the red 
from the prompt...but it's still very unusable.  And 720x576Over is 
stretched too far off screen.

Any help or a tip in the right direction would be more than 
appreciated...and if any other info is needed...logs, tests, 
whatever...i'd be happy to provide!
Regards,
Evan


The following is in my Xorg.0.log, so i assume the driver is working 
properly:
(II) VIA: driver for VIA chipsets: CLE266, KM400/KN400, K8M800,
        PM800/PM880/CN400, VM800
(II) Primary Device is: PCI 01:00:0
(--) Assigning device section with no busID to primary device
(--) Chipset PM800/PM880/CN400 found
(!!) VIA Technologies does not support or endorse this driver in any way.
(!!) For support, please refer to http://www.openchrome.org/ or
(!!) your X vendor.
