Please just try xawtv. It's *so* much easier. Also, you're going to have issues unless you can get Xv working on your video card.
Xawtv is the only thing that works for me, and I'm glad you suggested it. But the goal is to have MythTV work. I want to take the next baby step.
I want to see live tv via MythTV next (which currently displays a blank screen). I'm sure there's a smaller step I can take to get there. What other tests and troubleshooting can I do, knowing that Xawtv works, but mplayer doesn't, and I can't even cat from /dev/video0?
Stop trying to 'cat' from /dev/video0. You're not supposed to do that with a framegrabber card; that test is meant for hardware MPEG encoder cards like the PVR-250, that allow you to read an MPEG stream from the video device. DON'T DO IT!!
What exactly is Xv? Is that something that MythTV
depends on?
Yes. Xv is the X11 extension that enables 2D scaling of video to be done by your video card hardware. Without it, your CPU must shoulder the load. If you're recording at, say, 640x480, but your display resolution is 800x600, then to display full-screen the video must be scaled. Doing the scaling in software is quite taxing on your CPU, hence the need for Xv, so you can let your video card do it. Without Xv, I doubt you'll be able to watch LiveTV on a PII-400 or whatever it is you have. That's a pretty lightweight box to try and serve as a combined backend/frontend IMHO, even *with* Xv.
