The mplayer test I've seen folks use to test also fails:
[EMAIL PROTECTED]:/home/mythtv# mplayer /dev/video0 MPlayer 1.0pre5-3.3.4 (C) 2000-2004 MPlayer Team
I got a slightly better failure with the following:
# mplayer tv:// -tv driver=v4l # mplayer tv:// -tv driver=v4l2
Try specifying a channel, as in "mplayer tv://3"
Instead of seg faulting, it at least pops up a window, but nothing appears in the window. The terminal window fills with the error:
v4l2: ioctl dequeue buffer failed: Input/output error, idx = 0
This is the complete terminal window output:
MPlayer 1.0pre5-3.3.4 (C) 2000-2004 MPlayer Team

TV detected! ;-)

Hmmm, interesting. MPlayer is only detecting one input: Composite1. It doesn't appear to be detecting the tuner.
Current input: 0
So, your current input is Composite1. I'll be if you had some input going into the composite connector on your TV card, you'd see some video. You want the input to be TunerX (probably "Tuner0"), but MPlayer isn't auto-detecting it. You could try passing the "-input" option to MPlayer, as: "mplayer tv://[channel] -tv device=/dev/video0:input=X",
where "X" is a number (typically 0 - 4 or so). Right now it's defaulting to "0", try 1,2,3 & 4.

It seems there is no Xvideo support for your video card available.
Run 'xvinfo' to verify its Xv support and read DOCS/HTML/en/devices.html#xv!
See 'mplayer -vo help' for other (non-xv) video out drivers. Try -vo x11
You'll definitely want to address this eventually; for now you could try "-vo sdl", "-vo gl" or "-vo gl2". Use "-vo x11" as a last resort.

My guess is that MPlayer is not able to see/handle your tuner. Perhaps the kernel module for your tuner needs to be configured. Depending on your distro, this would be done in /etc/modules.conf or /etc/modprobe.conf. As to why Xawtv works, perhaps it's better at auto-detecting things.
