Have you looked at the TV-out info on the softdevice web page:
It was a while ago that I set my G450 up but I think it was pretty
straightforward. Here's hoping that someone will correct me here!
One thing I _can't_ remember is whether the stock matroxfb in the kernel
source works or whether it needs replacing with a different version
(maybe someone else can enlighten us on this!). You will need a couple of
patches which are to be found in the DirectFB source:
matroxfb-g400-clock-2.6.6.patch.bz2 (not quite sure what this one does)
matroxfb-full-memory-linux-2.6.6.patch.bz2 (this lets you use all of the
RAM literally changes a couple of lines)
It looks like the matroxfb-vsync-irq patch has been included in the stock
kernel so isn't needed now.
I made a component RGB cable from the schematics at:
(pretty sure it was the "Scart-RGB cable for the Millennium G450" one
which I bodged from a lead pinched off an old monitor.
Apart from that, I think I just built CVS DirectFB, CVS softdevice and it
all just worked, apart from I was seeing lots of horizontal lines when
scaling to a 4:3 TV (fixed by setting softdevice to 16:9 and setting my
TV to 16:9 or 4:3 as needed!), although I think that has been resolved
As I mentioned in a previous posting it was working perfectly until I
updated softdevice a few weeks back. Now the A-V sync sometimes wanders
and interlaced streams aren't always smooth. Yet to track down the cause
