Philips 7134 TV tner Card

I just got this PC TV tuner card based on the Philips chipset and can't
seem to get it to work. WIN XP recognizes that there is a card, but
when I try too load the drivers, XP says it can't find the drivers even
though they are there on the disk. Has anyone had a similar problem?
Not sure if card is bad or not. I tried it on another PC also. On
that one, also with XP, it loaded, but I couldn't get the tuner to show
any video signal, just blurred lines came up..

If you look in the driver install directory, there will usually
be a .INI file (this assumes the driver is a ZIP file).

Here are a couple lines extracted from a 7134 card driver .INI file:

%Cap7134.DeviceDescProtFQ%=Cap7134.DeviceFQ,PCI\VE N_1131&DEV_7133&SUBSYS_48411043
%Cap7134.DeviceDescProtFM%=Cap7134.DeviceFM,PCI\VE N_1131&DEV_7133&SUBSYS_48431043

The PCI/VEN portion identifies the major chip on the PCI card.
In this case 1131 would be Philips.

The DEV part is the chip made by Philips. Here are a couple possible devices.
Yes, the numbering does seem a bit counter-intuitive.

7134 SAA7134HL Multi Media Capture Device

The Subsystem part is not listed anywhere. Subsystem is a further refinement
of the enumeration of the PCI card. In the case of TV tuner cards, it allows
the driver to figure out which company made the card. And, in the case of
TV tuner chips, it might help identify which input on the chip, has which
kind of device on it (baseband video, tuner etc.) The tuner card can also
contain a serial PROM, and further probing of that information tells the
driver about the tuner manufacturer, whether FM is present, whether there
is stereo, closed captioning and the like. But probing of the serial PROM is
not required as part of the driver install process, so there is no need
to know anything about it just to install a driver. At this point, all
that is needed is to match PCI/VEN/SUBSYS, to kick off the install process.

Now, for a driver to install, Windows will look in the .INI and see if the
PCI/VEN/SUBSYS of the actual card, matches anything inside the file. If
it doesn't find a match, then Windows will conclude the driver is not
intended for the card.

I believe it is possible to modify the .INI file, and in the case of
non-TV tuners, you could remove the "&SUBSYS_48411043" portion from
a line in the file, to make the driver "match" any card with a 7134
on it. But in the case of the TV tuner card, this would be a dumb thing
to do, because when you use some control panel to select the tuner or
a RCA video input jack, the card will do the wrong thing. (It won't
know the mapping between the ports on the chip, and how the card is
wired.)

All I can suggest you try at this point, is if you have a copy of Everest
Home Edition (no longer available for download from lavalys.com), you could
perhaps get the PCI/VEN/SUBSYS info for the card. At least then, when you
search the net for a driver, you'll have some way to tell whether you are
getting closer to the right one or not. (Sisoft Sandra might also be
able to give you this info, but I haven't tried a recent version
and don't know if the free one still does that for you or not. If you
were using Linux, "lspci" is a program that can list hardware.)

( This site contains a list of devices, and that is how you could
potentially figure out what a totally unknown PCI card is. The file
size is 192KB or so. But SUBSYS fields are not listed for hardware,
so this cannot tell you exactly who made a card - it just tells you
who made the major PCI chip on the card. )

Just for interest sake, the SUBSYS field contains two numbers.
THe 4841 part and the 1043 part are actually separate. 1043
stands for Asus, and seems to be consistent from driver to
driver, implying there is a manufacturer registry somewhere.
The 4841 part identifies which TV tuner card this is, that
Asus made. I expect only the company writing the driver,
knows what 4841 means. I doubt there is a central registry
for it.

If you had posted some info about the manufacturer of the card
and what model the card was, it might have been possible to search
for a driver for it. But knowing how many TV tuner card types
that are out there, finding a driver might be as hard as
finding a driver for a Winmodem :-(
