Post subject:  DVB cards gets mixed up at boot ?
I have 3 PCI DVB cards and 1 USB DVB stick in my MythTV backend box.
(WinTV Nova, 2*Technotrend (SkyStar 2), Hauppauge USB Stick)

I can configure them fine in the backend, tuning them to correct channels and all,t when I reboot the machine, sometimes - the cards gets mixed up (like Card0 gets to be Card1) - which ofcourse results in no liveTv working.

Is there anyway to force the cards to a specific Card number ?

Or has anyone else experienced this ?

Yes. You can do this through the "udev rules" configuration. Searching for the quoted terms should find the recent discussions of how to do this.

hmm.. tried following the setup...

It looks like I can control what is /video0 and /video1 - but when it comes to the dvb devices ? still random - perhaps I am not targeting them correctly.

I use dvb/adapter0 and so forth ? in the local.rules file

Looking at my post here you will probably have to use udevinfo -a -p devpath to identify what is distinct about each card.

Post subject:  looks like working...
Thanks !

I did actually have a look at that post, but could not located the ID of the other DVB cards, but it seems to work if I make a match in the .rules file on the name of the dvb card.

I thought it worked...

but it didn't ?
being a newbie in the Linux world.. it is probably something stupid..

What should

SYMLINK=+ point to ?
and
NAME ?

I think it is a bit different setup I have got, as my two DVB-S cards are SkyStar2 cards - so they won't appear as video0 / video1, they will appear as "dvb/adapter0" in the /dev directory.

Can anyone help ?

Udev is fairly new, I'm not entirely sure about udev myself. :)
I would ignore the the Symlink statement, I couldn't use the this for the setup of the card in mythtv-setup anyway.
What is the card that seems to move about the most? At a wild guess I would probably say the USB one, it might be worthwhile tying this one down.

I have a suspicion it doesn't matter, so if you call it /dev/usbdvb or /dev/skystardvb1 there shouldn't be a problem.

Post subject:  well..
I am actually only concentrating on 3 cards at the moment, and those 3 are PCI

2*budget_ci dvb (skystar2 PCI)
1*Win-TV Nova (dvb-t)

It looks like the budget cards stays together, so I would say that it is the Nova card that is either first or last.

Funny thing is that when I look at the attribs for the budget cards, I cannot identify them my attrib {name} - but I guess it is OK to identify them by {irq} instead...

As I mentioned in another thread last night the PCI bus id is also a good choice. Use lspci and the numbers in the first column are your Bus IDs.

Post subject:  still no luck
the linux newbie thing is still bugging me :lol:

tjc -> can you post a working line from your local.rules file ?

I tried both the irq's and the bus id - but still no luck, the cards are still shuffled like a deck of cards... beginning to get quite annoying.

I can see that the card that I want as "Card0" is card "0" if I look at (card type) "MJPEG" under Video Device => "/dev/video0"
But when I look in the (card type) DVB DTV it still shows up as DVB card number 2 ?
