dvbscan not working with Pinnacle TV PCI card. "Failed to open frontend"


I have a PCI Pinnacle TV card. I was not able to identify the exact model, but it has a Broktree bt878 chip. The input I want to use is a standard TV cable (http://image.made-in-china.com/2f0j0...f/TV-Cable.jpg). When I use dvbscan it returns "Failed to open frontend". Card is detected with lspci as

01:01.0 Mutimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

I want to detect digital terrestrial TV. I'm from Italy.

What is causing this?

First things first, you will need to have software support for it.
If you have software support installed in your machine for your card, and you have linuxtv-dvb-apps installed,
Use your own paths, and you use dvb-t don't you?
Code:
scan /usr/share/dvb/dvb-t/it-All
Take the output of that and make a channels.conf, put it where your media player can find it.
Then use a player to watch or record digital tv. Example
Code:
mplayer dvb://
Then use the h and k keys to change channels or
Code:
mplayer dvb://WABC
To watch a particular channel

"Failed to open frontend"
Use scan then instead of dvbscan.

It didn't work. Using

Code:
scan /usr/share/dvb/dvb-t/it-All
results in this:

Code:
scanning /usr/share/dvb/dvb-t/it-All
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
main:2745: FATAL: failed to open '/dev/dvb/adapter0/frontend0': 2 No such file or directory
As far as I know, this device is Linux kernel supported.
The card is detected by the system. Here the output of lspci -v

Code:
01:00.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
	Subsystem: Pinnacle Systems Inc. PCTV pro (TV + FM stereo receiver)
	Flags: bus master, medium devsel, latency 64, IRQ 17
	Memory at dfffe000 (32-bit, prefetchable) [size=4K]
	Capabilities: <access denied>
	Kernel driver in use: bttv

The error shows that you,
Don't have the device plugged in
Don't have software support on your machine
The device doesn't work.

You sure that isn't an analog device?

I can be sure about it being plugged in. At least, as much as it being detected by lspci means. Searching around, I found that the bttv module in the Linux kernel offers support for the bt878. About it working, I can't be 100% sure.

The part about it being an analog device, well, that could be. As stated before, it is a quite old Pinnacle TV card. There is a way to know if it works? Analog TV is no more here, only digital.
