Pvr 350 Ivtv Help! Tuner 47


For the past couple of weeks ive been trying to get my Hauppauge PVR 350 to work under linux, but i seem to be failing somewhere since all my channels are static. I finally decided to dual boot windows just to make sure the card worked. To get the channels to tune under windows i had to download the newest firmware from the hauppauge site and also had to set the cable input to cable-hrc in wintv2000. Here is my system information

Debian Linux Unstable
2.6.8.11-rc3 kernel
pvr-350
ivtv-0.2.0-rc3f
My tuner is type # 47.

so here is what ive done...
downloaded linux 2.6.10 and patched with 2.6.11-rc3 patch
downloaded ivtv-0.2.0-rc3f
downloaed ckennedy's recommended encoder/decoder pvr48wdm_1.8.22037.exe
make && make install driver and utils

i then created the /dev/video
# mknod /dev/video0 c 81 0
# mknod /dev/video16 c 81 16
# mknod /dev/video32 c 81 32
# mknod /dev/video224 c 81 224

i then edited /etc/modutils/ivtv and added
alias char-major-81 videodev
alias char-major-81-0 ivtv

#update-modules
#depmod -ae
#modprobe ivtv

here is the output from /var/log/messages |grep ivtv

I think i have everything set up correctly, but when i cat /dev/video0 > /tmp/test.mpg

the file is just static.
when i change the channels in mythtv they are all static as well.

am i overlooking something? do i need to add anything to /etc/modules.conf

Anyone have any suggestions

thanks,

jeff

Try using tuner=39 for the ivtv module option. Use ptune.pl or ptune-gui.pl to change channels because sometimes MythTV does not work. For kernel version 2.6.x, the auto-loading module file is /etc/modprobe.conf. You need to make sure msp3400 and saa7115 modules are loaded, but I think they are already loaded from the logs.

thanks for the reply.

ok, so i set my tuner to type 39, and i still see static, but im also seeing several hundred lines in /var/log/messages now that look like the one below

Feb 10 20:12:03 localhost kernel: ivtv: ENC IRQ OVERFLOW: #1838 Stealing a Buffer, 1024 currently allocated

also if i try to rmmod ivtv after closing mplayer and ptune-ui and kill all ivtv processes i get a message saying
ERROR: Module ivtv is in use

so now i have to restart my computer to unload the ivtv module :/

ok so i figured out how to rmmod ivtv... apparently even after closing mplayer, the process still hung around so i had to kill the mplayer process, but im still confused with the static and also confused with the ivtv: ENC IRQ OVERFLOW: messages in /var/log/messages.

any other suggestions?

thanks,

Jeff
