I have been reading the 'TV-out, softdevice' thread and it appears there are users out there happy with their G450 + softdevice setup. I have a G450 but have been put off using it with VDR because information on how to get this combination to work on the net is poor. Googling gives information that is very old. Can anyone provide a concise howto describing everything required to set up a G450 head2 rgb-scart with softdevice on a recent 2.6.x kernel?

Have you looked at the TV-out info on the softdevice web page: http://softdevice.berlios.de/#TV-Out
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: http://forum.matrox.com/mga/viewforum.php?f=52&sid=a1c50e38759f99f96d4bf... (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 now.
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 of this...
Cheers,

It's probably the non-MMX scaler function that was introduced in order to properly scale the interlaced fields separately, to avoid distortions when the vertical resolution changes. I posted my findings about that on the softdevice list a couple of weeks ago.
