I have tried using kaffeine before, but it seems like it is only used for
DVB. Is it true? Because I can't figure out how it actually scan for
analogue channels. And yes, Malaysia uses PAL.
So first, to answer your question:
You have installed the firmware and necessary driver?
dmesg should show something about the card/driver being initialized.
Generally, dmesg reports the hardware socket which is created. You should
see a /dev/video0.
This is what it reports

And so far, in MythTV, it does have the correct probed info. But it does not
scan. I wonder why.
