I forgot to mention some HD stuff related to video output.
Even though EPIA boards with the CN400 can decode HD (once the problems
with MythTV are fixed), then cannot necessarily output HD using the TV
output. For that, the board needs an HD capable TV encoder chip. The VIA
EPIA SP series does not have one. The VIA EPIA equivalent board from
Commell does have the HD capable TV encoder as does the VIA EPIA EN
series board. However, while there has been off and on work to get the
HD capable TV encoder working in the Openchrome drivers, I do not
believe that it is done yet.
One might consider using the DVI output using the DVI addon module, but
I do not believe that is supported by the Openchrome driver.
That leaves VGA, which is what I use. However, the picture quality usin
the DVI on my ASUS board is better than using either the VGA on my VIA
board or the VGA on my ASUS board.
