[mythtv-users] Question about configuring X for PVR-350

[Robert Buchanan]

Hello,

I (like a few others) from what I can gather am having trouble getting
TV playback through the S-Video TV-out on my PVR-350 card. When I follow
Jarod's guide to configure the card and test it, everything seems to
work OK. I am able to

dd if=/dev/video0 of=/dev/video16 bs=64k

and see TV output, and I can hear the audio. Now I'm checking to make
sure that I have X configured correctly to run on the PVR-350. I think I
have a problem somewhere. X starts up and things look fine on my
computer's LCD display (connected to my video card via a DVI cable). On
the TV screen I see a blank blue screen. Should I be able to move the
mouse cursor onto the TV screen? I can't at present. When I enable
PVR-350 output in the setup/utilities of the mythfrontend and then go to
watch TV, I get an error message about audio rates not matching, the
opprtunity to continue without audio, which I select, and then the
mythfrontend quits on me. When I disable PVR-350 output, I can watch TV
just fine.

What am I doing wrong? I have included some information from my system
below. There is an error message generated by X and configuration info
on the hardware.

Thanks,
Bob Buchanan

# from /var/log/Xorg.0.log
(--) Chipset PVR-350 found
(EE) open /dev/fb0: No such device
(EE) Screen 1 deleted because of no matching config section.
(II) UnloadModule: "ivtvdev"

But I do have a /dev/fb0 device with the following permissions, etc.
# ls -l /dev/fb0
crw-------  1 mythtv root 29, 0 Feb 23  2004 /dev/fb0

I have checked the output of /var/log/messages to see which frame buffer
is being grabbed.
# cat /var/log/messages | grep iTVC15
Mar 22 21:36:15 localhost kernel: ivtv: Found an iTVC15 based chip
Mar 22 21:36:18 localhost kernel: ivtv-osd: fb0: iTVC15 TV out frame
buffer device

I have checked the bus-id of my PVR-350 card.
# lspci -v
2:06.0 Multimedia video controller: Internext Compression Inc iTVC15

        Subsystem: Hauppauge computer works Inc. WinTV PVR-350

I used this information to customize my xorg.conf file. Did I understand
what
to modify correctly? Here is my xorg.conf:
