Post subject:  PVR350 tuner setting goes to the BTTV card
Hi,
I have successfully installed Knoppmyth with a PVR-350. I also did a previous installation with a bt878 card which was autodetected fine.

My problem is to use the combination of the two.
I got the PVR-350 fine but I can't set the tuner right for the bttv

Here is the output of the dmesg

As you can see it looks that the setting for the ivtv tuner goes to the bttv card.

And here my cards configurations:

ivtv
Code:
alias char-major-81 videodev
alias char-major-61 lirc_i2c
options ivtv debug=1
options tuner type=44
options msp3400 once=1 simple=1
options saa7127 enable_output=1 output_select=1
add below ivtv msp3400 saa7115 saa7127 tuner
add above ivtv lirc_dev lirc_i2c ivtv-fb
post-install ivtv /usr/local/bin/ivtvctl -d /dev/video0 -u 0x3000
post-install ivtv /usr/local/bin/ivtvctl -d /dev/video16 -u 0x3000
post-install ivtv /usr/local/bin/ivtvctl -d /dev/video32 -u 0x3000
post-install ivtv /usr/local/bin/ivtvctl -d /dev/video224 -u 0x3000


bttv1
Code:
alias char-major-81-1 bttv debug=2
#post-install bttv insmod tuner type=2

#alias char-major-89 i2c-dev
#options i2c-core i2c_debug=1
#options i2c-algo-bit bit_test=1
#alias char-major-81 videodev
#alias char-major-81-1 bttv debug=2
#options bttv card=40 pll=1 tuner=2


I tried to put the tuner option and other options (commented in this example) but it did not help out.

Am I doing anything wrong ?

you may have a PVR-350 with a new tuner still not supported in an official kernel release. Try this:

modprobe tveeprom
dmesg|grep idx

You should get something like:

tvee: tuner=LG NTSC (TAPE series) (idx=68, type=47)

(yours would probably read tuner=unknown"

If you have idx=68 then you have the same tuner I've got. You have to patch the kernel sources and recompile modules. I have a couple of diff files to patch the kernel source that comes with R4V5. Email if you want them. My gmail account is spectro @ gmail.com

Now that I changed the ivtv file as you said both tuners are set to 2 which make the bttv card work now but also get my pvr 350 stuck on a channel.

Here is the output of the modprobe:
tvee: tuner=<unknown> (idx=68, type=-1)

Is there a way to force the tuner to 44 for the pvr350 and to 2 for the bttv card without going the recompile route ?

Thank you for helping.

For idx=68 use tuner=47, not 44. You need to patch video4linux in the kernel to support this new tuner. You can also use tuner=39 without recompiling, but you wont be able to see channels > 61

I get all the channels on the PVR350 with tuner=44. BTW tuner=39 does not get any channel on the PVR350 for me.
My problem is that both tuners are set to the same number whatever I tried so far.
Will recompiling help in this respect ?

I finally got it working without updating the ivtv driver :D

Do not use the:
options tuner type=XX

This will set the same tuner type to all the tuners
Also if you read your dmesg output you can see that it is obsolete.
Instead use:

Code:
options ivtv tuner=xx

for the ivtv file
and
Code:
options bttv tuner=yy

for the bttv1 file

I recorded 2 shows at the same time to do a test.
Unfortunately the show recorded on the bttv is to slow when played on the pvr350 output (using the PVR350 X driver) and I don't have the sound as it is played with the onboard sound card and not the PVR350 :roll:

I guess I will have to tweak the resolution as my set top box (Activy 300) is already using the 2 pci slots for the tv cards and is already maxed out (1400 Mhz celeron and 256 MB RAM).
