I agree completely with the sentiments of that posting. I also ran myth
with directfb to start with and the results were disappointing.

It is possible, but somewhat involved. Mine's a G550 and I run it under
X. There's no XV on the tv-out, so you need a decent processor to do
everything in software. Also no DMA, so you can only get 16 bit colour
due to PCI bandwidth, but you can get perfectly smooth video and the
results are pretty good generally.

There are some TV-out patches to X for G450 out there somewhere (google
for them), you might make progress with those. I use a somewhat re-
written version of matrox-tvout, written by Shaun Jackman. The last
version he published is on freshmeat, but he's got more recent stuff
than that if you mail him. It's written for the G550, but should be
hackable for G450.
