HDTV Wonder - analog portion isn't working

HDTV Wonder - analog portion isn't working

[Lee Alkureishi]

Hi everyone,

I'm hoping someone might be able to help me get the analogue portion of 
my ATI HDTV Wonder up and running. I've already set up the ATSC dvb0 
device, and am using it to watch HD content without problems.

When I try to watch tv using the second coaxial input (which is set up 
in mythtv-setup as an analogue v4l device at /dev/video0), I just get a 
black screen. Scanning for channels produces timeouts at every station 
(no signal). I'm mainly using mythtv (mythbuntu 8.04, mythtv 0.21, fully 
updated), but the same thing happens in tvtime and xawtv. I'm unable to 
find any channels.

My setup is an athlon 2400+, 512Mb RAM, nvidia GF 440MX, ATI HDTV wonder.

When I try to manually run v4l-conf, I get the following error:

leeko@leeko-media:~$ v4l-conf -c /dev/video0 -1
v4l-conf: using X11 display :0.0
dga: version 2.0
X Error of failed request:  XF86DGANoDirectVideoMode
  Major opcode of failed request:  137 (XFree86-DGA)
  Minor opcode of failed request:  1 (XF86DGAGetVideoLL)
  Serial number of failed request:  13
  Current serial number in output stream:  13

Running xawtv, I get a black screen, and it's fixed to 
"NTSC/europe-west" with no way to change it to us-bcast. Changing the 
channels produces nothing.

Troubleshooting, I tried this:

leeko@leeko-media:~$ xawtv -noxv -nodga

But it produces another set of error messages:

This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.24-19-generic)
xinerama 0: 1024x768+0+0
X Error of failed request:  XF86DGANoDirectVideoMode
  Major opcode of failed request:  137 (XFree86-DGA)
  Minor opcode of failed request:  1 (XF86DGAGetVideoLL)
  Serial number of failed request:  13
  Current serial number in output stream:  13
v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string 
"-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct
ioctl: VIDIOC_REQBUFS(count=2;type=VIDEO_CAPTURE;memory=MMAP): Success
ioctl: VIDIOC_REQBUFS(count=2;type=VIDEO_CAPTURE;memory=MMAP): Success

and when I try to change channel:

ioctl: VIDIOC_REQBUFS(count=2;type=VIDEO_CAPTURE;memory=MMAP): Resource 
temporarily unavailable
ioctl: VIDIOC_REQBUFS(count=2;type=VIDEO_CAPTURE;memory=MMAP): Resource 
temporarily unavailable


Please help! I don't know what to do next, to get this analogue input 
working!


Thanks in advance,

Lee

Lee, did you try scanning for analog channels on both RF inputs ?  What
is written on the PCI riser applies to the expected operation under a
Windows environment.  Under Linux, this may differ.  In fact, going
beyond the default behaviour one may observe under Linux, note that
mkrufky also added an option for dual RF input devices so that the user
can specify which input they want used for analog and digital. See
"modinfo tuner-simple"
