Hi,

"The Fools" have been at work again, and have some very interesting news...

Jim Beacon discovered that the later nVidia driver we're both now using for our cards permits pixel clocks below 12MHz.

I've worked out a new modeline for 405-line using a pixel clock of 6.48MHz, which gives me even closer 405-line timings (line and frame rate are exactly 10.125kHz and 50Hz respectively) and has a rather more respectable 536 x 378 resolution.

One upshot of this is the MythTV user interface is a lot more readable as the text isn't squashed; the user interface settings still need a bit of a tweak, but it's a vast improvement.

Details of this will be added to the website in due course.

Regards, Kat
