i am running ubuntu 6.06 with kernel 2.6.15-26-386 and using ivtv-0.4.6. I can capture video off the tuner and transfer the file to my laptop and play it just fine. When I execute dd if=/dev/video0 of=/dev/video16 bs=64k I get audio but no video. I also followed Rachel’s howto to get x working with my pvr-350 but I get these errors when executing startx

Couldn’t open RGB_DB ‘/usr/X11R6/lib/X11/rgb’

Can you show how you setup tvout for dapper?

Thanks for setting up this page. Just did this for my pvr350 using Ubuntu Breezy (5.10), with linux kernel 2.6.12-10-386 and ivtv 0.4.2. It still works (usuing slightly adjust directories), with the following differences (for me at least).

1) There was no ‘extra’ directory in /lib/modules/[kernel version], so I didn’t need to move those modules anywhere.

2) There was an ‘ivtv’ directory created under /lib/modules/[kernel version], and I had to copy this directory to /lib/modules/[correct kernel version]/kernel/drivers/. ( & do depmod)

3) After rebooting, I was getting errors in dmesg saying

ivtv0: unable to open firmware v4l-cx2341x-enc.fw
ivtv0: did you put the firmware in the hotplug firmware directory?

I had to copy the ivtv firmware from the /lib/modules directory to /usr/lib/hotplug/firmware; also there was a file called v4l-cx2341x-init.mpg in the ivtv-0.4.2 (source) directory that I also had to copy to /usr/lib/hotplug/firmware; I had to link the ivtv-fw-dec.bin and ivtv-fw-enc.bin firmware files to v4l-cx2341x-dec.fw and v4l-cx2341x-enc.fw, and make sure they were all executable. Then the errors stopped and the card worked.

There is some further info here that might be useful:

“Firmware
Extract the firmware and put that in /lib/modules”

What do you mean with this? A little more info would be nice.

I’m unable to do ‘make’ on the ivtv drivers in ubuntu. I do have the kernel source installed, but i get a huge output of thousands of errors on make:

make[1]: Entering directory `/usr/src/linux-source-2.6.10′
CC [M] /usr/src/ivtv-0.3.6i/driver/msp3400.o
In file included from include/linux/module.h:10,
from /usr/src/ivtv-0.3.6i/driver/msp3400.c:38:
include/linux/sched.h:4:37: asm/param.h: No such file or directory

asm/param.h is located in /usr/include, so I dont get whats going on, or how I can fix this compilation. Any help would be appreciated.

I’ve added some instructions for getting X working on the TV-out from the PVR-350 card, and the full example xorg.conf file.

I’ll add a couple of thoughts about troubleshooting too.

What does you xorg.conf file look like? How did you actaully get the output to the TV?

I have expanded some on your instrustions some at my website but I am waiting to publish them until I get the x output going.
