I've playing around with LinuxMCE on my workstation before I dive into spending money. I have two ATI video cards...both with S-Video out. During the console bootup and pre-X I can see images just fine on my Apex TV. However when I start X and I can no longer see anything besides streaking on the TV. I've changed the resolutions and everything I can think of with the Resolution Settings (Step 1). I've changed the jumper from PAL to NTSC on one of my ATI cards and still having streaking and I can't even begin to see video.
Should I look at a NVIDIA card? I don't care about spending the $40 for a video card if I know that's the problem...
