Hi List,
I am trying to build Linux Media Center with Tuner card removed from
MyTellyHD (Interact-TV). MyTellyHD used to work with this tuner card.
However on my Linux machine (Fedora 12 beta) I do not get picture or
sound when I do 'mplayer /dev/video0'. I just get black screen. I am
using composite signal output from Digital Satellite Box (works on
TV).

I see suspicious message in dmesg - “Invalid EEPROM”. Is that a problem?

This card is unknown to the kernel's ivtv driver.

It appears it is a Provideo Multimedia PV-967C a card for which I can
find almost no information except for a low-resolution picture on this
page:

http://www.nucleuscomputer.com.au/provideo/Multimedia.htm

It has no analog tuner, a CX23416 chip, and two other chips that I
cannot make out. Only two other cards supported by the kernel's ivtv
driver are like this, and neither one of them looks like the PV-967C.


You are an owner of a MyTellyHD, and I believe you have a modified Linux
kernel on that device. *If* that is the case, under the terms of the
GPL, *you* are entitled to the source code modified by Interact-TV that
corresponds to the binaries that Interact-TV distributed.

Please verify that your unit runs a linux kernel, and then politely
request of Interact-TV that they provide you with the modified linux
kernel source code, per the GPL. If they balk, tell them that all you
really want in the modifications made to the kernel for the MPEG capture
card with PCI id 1540:9673 (which I think is a Provideo Multimedia
PV-967C).

If you can easily obtain those modifications, then supporting your card
will be easy. If you cannot, then I'll need high resolution pictures of
the card, and we'll have to go back and forth through a series of
testing and patches on the ivtv-devel list.

> I see suspicious message in dmesg - “Invalid EEPROM”. Is that a problem?

No. Your card's PCI ID, and hence configuration, is unknown to the ivtv
driver.

Here's an excerpt from Interact-TV's software license agreement:

"Open Source Components:The Telly contains numerous software components,
each of which was written and copyrighted individually. Some of these
software components are licensed pursuant to the GNU General Public
License GPL that permits you to copy, modify and redistribute the
software, in both source and binary code forms. To request more about
the open source software modules included in Telly, please send an email

that component. A copy of the GNU GPL can be obtained from www.gnu.org"


So it looks like you should send the email to: info@interact-tv.com .


Regards,
Andy

Thanks Andy,
I have already sent email to Interact-TV, I will update list when I
get some response from them.
