[linux-dvb] Pinnacle PCTV Media Center 300i PCI Card

[Rainer Schubert <lintv@dl6hbo.inka.de>]

Hi,

in an earlier thread I read about that card after I had bought one, which
works happily under WinXP, but delivers just a snowy image under Linux.

I use the insmod option "card=26" as advised in that earlier thread and
here are the messages I get using "dmesg" on an 2.6.9-1 kernel on a
Debian Linux system.

saa7134[0]: found at 0000:00:0c.0, rev: 1, irq: 209, latency: 32, mmio:

saa7134[0]/audio: audio carrier scan failed, using 5.500 MHz [default]
tuner: TV freq (0.00) out of range (44-958)

As far as I can see the problem is the Zarlink MT352 DVB-T demodulator,
which seems not to be recognised by the definition for the card #26.

I have been trying hard to learn more about that card and have now
modified my insmod command line like this:

modprobe saa7134 card=26 audio_debug=1 core_debug=1 i2c_scan=1

Here is what dmesg has to say to the above:

saa7130/34: v4l2 driver version 0.2.12 loaded

tuner: Ignoring new-style parameters in presence of obsolete ones

saa7134[0]: registered device video0 [v4l2]

So as far as I can see there are five devices on the card:
MT2050  @ 0xc0
TDA9887 @ 0x86
eeprom  @ 0xa0
??????  @ 0x3c
??????  @ 0x8e

According to the docs there are these chips on the card:
1. SAA7134           Video decoder                      found
2. MT2050            TV-Tuner                           found
3. TDA9885           Analog demodulator                 found
4. MT352             DVB-T demodulator                  missing
5. Should be the eeprom, not mentioned explicitly       found

I have read, (but not fully understood) :
/usr/src/linux/drivers/media/video/saa7134/saa7134-cards.c
and understand that the definition for the Pinnacle PCTV Stereo
card (#26) does not include the MT352 DVB-T decoder in any way.

Now my question(s) to this list:
How do I write a correct definition for my card ?
What else will I have to do to make it work ?
Is any of the chips mentioned above need a firmware file loaded,
say by hotplug or compiled in, to make it work ?

Any help is welcome.

And sorry for pestering you all :-)

Regards,
Rainer
