Post subject:  PVR 150 tuner is not recognised [partially solved]
I have installed KnoppMyth R5A16 on an old Pentium II 450 on a 440BX mobo with 256 Mb of ram.

The problem is that I cannot get a good picture from the PVR150 card. The card also does not react to commands given by ptune-ui.

The cause is that the tuner of the PVR150 is not correctly identified. I have tested this card on a Nforce 2 AMD system with Gentoo and it works perfectly there with ivtv 0.3.6x. The tuner is detected there as type 55.

Because the default 0.2 drivers included with KnoppMyth do not work for me I have compiled the 0.3.6x drivers. When IVTV is loaded, dmesg gives the following:
Code:
ivtv: Autodetected WinTV PVR 150 card
ivtv: Found an iTVC16 based chip
ACPI: PCI interrupt 0000:00:10.0[A] -> GSI 9 (level, low) -> IRQ 9
ivtv: XXX PCI device: 0x7190 vendor: 0x8086
ivtv: i2c attach [client=(tuner unset),ok]
tuner 1-0061: chip found @ 0xc2 (ivtv i2c driver #0)
saa7115: starting probe for adapter ivtv i2c driver #0 (0x10005)
ivtv: i2c attach [client=tveeprom,ok]
tveeprom: Hauppauge: model = 26034, rev = C197, serial# = 7729955
tveeprom: tuner = <unknown> (idx = 97, type = -881607032)
tveeprom: tuner fmt = PAL(D/K) (eeprom = 0x44, v4l2 = 0x00000e07)
tveeprom: audio_processor = MSP3400C (type = 4)
ivtv: Tuner Type -881607032, Tuner formats 0x00000e07, Radio: yes, Model 0x008d1657, Revision 0x00000001
ivtv: PAL tuner detected
ivtv: Radio detected

You will notice that ivtv gives a completely bogus Tuner Type.

I have had the PVR 150 in different PCI slots but it doesn't make any difference. Also removing all ivtv related modules from the kernel and doing
Code:
modprobe ivtv tuner=55

Does not change things.

Can anyone help me?

No solution yet. I'll try also the ivtv development list.

Hmmm....Someone can set me straight, but...but isn't that what the

/etc/mythtv/modules/ivtv

file is for? If I recall correctly, if you put your ivtv settings in that file, they override the
settings that ivtv automatically detects.

Also, the file "set_ivtv_params"
in the
/etc/init.d

contains certain ivtv settings, which you can set manually. If I'm right, you should be
able to find the answers you're looking for just by searching the forum with those paths
and filenames as keywords.

Can someone confirm this?

It turned out that the /lib/modules/2.6.11.9-chw-2/v4l2 also contained tuner.ko, tda9887.ko, and tveeprom.ko. These modules interfered with the ones from ivtv 0.3.6x. After renaming these modules everything works fine. ivtv correctly identifies the tuner as type 55 and I have audio and video.

The install routine from ivtv-0.3.6x and 0.3.7a both did not warn for these extra modules.

Post subject:  hmm
da..
i cant get it too work
just seeing static snow and noting else ...

i have a fev questions too you..

1.
what do you write in your /etc/mythtv/ivtv file
2.
What do you use in your mythtv-setup as your tv setup card (mpeg 2 ( pvr 250 - pvr 350 ) or V4l setup ??
3.
Which ivtv version do you use
4.
have you made any changes in other files ???


Please post back thanx couse iam going NUTS over this ...

Post subject:  Re: hmm
DaffyDk:

Hmm....turns out I had remembered wrong. "set_ivtv_params" looks like a script,
so best not to touch it if you're a newbie.

On second check, it looks like that configuration file is:
/etc/mythtv/modules/ivtv

I believe that's the file to which you were referring? Mine contains exactly what was
in the KnoppMythWiki PVR-150 HOWTO.


As for mythtv-setup card settings I have:
Card Type: MPEG-2 Encoder card (PVR-250, PVR-350)
Device: /dev/video0 (the first tuner card in the box)
Default input: "Tuner 0". (for tuner input, rather than, say VCR in)

Usually, if you're getting snow on your screen, that means you're almost there.
It suggests your tuner is at least partly working , but you're not getting a video signal
into it or you're not tuned into a channel.

If you're still having trouble:
Did you try capturing with the "cat" command in Linux and playing it back?
Did you check that there were no other lirc kernel modules present?

The ivtv FAQ includes instructions on how to do all of the above and much more:
http://ivtv.writeme.ch/tiki-view_faq.php?faqId=1

You'll have to figure out for yourself how not to do overlapping procedures,
so that you don't do the same things more than once, or do
things inappropriate
for your card, but the ivtv HOWTO is very helpful. http://ivtv.writeme.ch/tiki-print.php?page=IvyTvHowTo

Finally, what is your source? Antenna? Cable? Dumb question, but is it plugged in?
Are you getting a picture if you plug a TV into that source?

Hope this helps.

Wow thanx

Well i sort of got it too work
if i do
ptune-ui.pl
i can set the channels i want and then i do a cat /dev/video0 on it and it do capture video but no sound tho
but the picture are nice and fine when playing it back in mplayer

sooo yes the cable are pluged in (*lol*)

But then i turn on mythtv the channel are still there but after reboot its gone hmm dont get it..

Soo i exit the mythtv again and i open a terminal and type the rmmod ivtv and modprobe ivtv and the parameters after that and do a ptune-ui.pl again and then it works again .. but next time i reboots its gone

i belive that it cant hold the channels or the PAL or the frekvenz table or somthing like that

i used too run Media Portal in windows with no problems at all soo i know that the TV card are OK

thats my ivtv setting

I have installed KnoppMyth and I did not change anything on those files.

What I have working right now is switching channels with ptune-ui.pl and watching tv with mplayer /dev/video. So I know that ivtv is working.

i have not tried mythtv itself yet.

On my other system I have configure mythsetup with mpeg2 card for the PVR 150MCE but the PVR 150 is the same.

Right now I use ivtv 0.3.6x. I had to delete a number of modules the v4l2 subdir of the kernel modules directory.

Mythtv is not happy right now :-(.

When I try to watch tv with mythtv I get a black screen and after about 30s I get back to the main menu.

When I start mythfrontend in an xterm I get the following output

Daffy:

Well, if you do some searching of the forum, you'll see a lot of posts about sound issues-it's usually not hard to fix.

As for the instability with picture, I'm not sure about that one. It's probably best if one of the real experts around here comments on that.

Again, I'm just a semi-newbie, but I had to change the permissions on one of my folders
or files to get the buffer to fill. I recall the cache folder needing a change in permissions
before mythtv could read it, or something like that. (I assume you're logged
on as mythtv).

There are quite a few posts on the forum about black screen, returning to the menu,
so if my above suggestion doesn't help, a search should yield the solution.
