I bought an ECS A740GM-M MB and am trying to use it as a frontend for mythtv. I'm not having any luck with the video. Checking AMD/ATI website doesn't show this board being supported by their linux drivers. I can SD to play pretty good using their driver, but not an HD stream. Anyone have a 740G chipset board working in HD with mythtv?

Generally ATI is not recommended for Linux. They just don't accommodate us for drivers. nVidia is much better; get the 9300 or 9400.

I just couldn't pass up this deal. $65 for the MB and X2 5600+. I know I could use an Nvidia board as I have 3 of them already, 6100, 6150, 7050PV. I want to get this to work if possible. It's a spare. I found one post about adding some options in xorg. Will try that next.

Ok. Got it working great, thanks to this;

That's using Mythbuntu 8.04 and the ati fglrx driver. Smooth playback even when fast forwarding. Used the normal playback setup and also another I configured using other renderers. Both work great so far. If i run into any other problems I'll post them here. Oh, sound didn't work out of box. had to change that too. Several things work. Right now I'm using /dev/dsp with /dev/master I think. Anyway it's works good too now. Had that working earlier.
