Title: Message

Greetings. Sorry for
such long E-mail.

Now I am doing a
project about enable a Philips SAA7134 DVB Tunner Card (Compro VideoMate T300)
in a Linux machine, with a Linux kernel 2.4.26.

I have tried the
following methods but it still cannot enable the card.

1. compiling the
driver provided by http://linux.bytesex.org/v4l2/saa7134.html

2. compiling the
package provided by http://linuxtv.org

I first compiled a
new clean 2.4.26 kernel, with "Video for Linux" and "I2C support"
(module).

Then, I compile
the saa7134 package (stated at 1) and install it, and I compiled and install the
linux-dvb package, with the new kernel.

But when I execute
the linux-dvb-apps "scan", the following warnings appeared:

[root@localhost
scan]# ./scan ./dvb-t/au-sydney_north_shore
scanning

'/dev/dvb/adapter0/demux0'
main:2247: FATAL: failed to open
'/dev/dvb/adapter0/frontend0': 19 No such device

and here are the
message dump:

This TV tuner card works well in 2.6.16.18 kernel, as I
found that 2.6 use the driver "saa7134_dvb" instead of "saa7134", but this
driver "saa7134_dvb" does not appear in 2.4 kernel series. 

Please help. Thanks
for your time.

Best regards,
