I originally posted this on Myth-Users but the thread died a quick death. So, I'm posting here in hopes that someone can help me. You can read the thread below.

Essentially, I have two pcHDTV cards in a Myth box. Both cards work but only when one card is installed. Myth won't see nor use both cards. It seems I have only "adapter0" in my /dev/dvb/ directory. A second adapter directory is not being created when the dvb module loads. How can I fix this?

I purchased a second pcHDTV card for my MythTV box. I installed the
card and followed the instructions at:
http://www.mythtv.org/wiki/index.php/Configuring_PCHDTV_card_for_ATSC

It says:
For capture cards you will want to create one card config. Change the
type until it says "DVB", at that point it should show the name of
the card, "pcHDTV...". If you have multiple DVB cards you need to
change the device, to the one for the newest card. For pcHDTV cards
an "Analog Options" button will be present, click this if you wish to
use the analog portion of the card. If you have multiple V4L cards,
you will need to change the devices to the one matching the current
pcHDTV card.


My Capture Card Setup is:
Card type: DVB DTV capture card (v3.x)
For DVB Card Number 0, the Frontend ID is "DViCO v2 or Air2PC v3 or
pcHDTV HD-5500" and Subtype is "ATSC".
For DVB Card Number 1, the Frontend ID is "Could not open card #1"
and Subtype is "No such file or directory".
For DVB Card Number 2, the Frontend ID is "Could not open card #2"
and Subtype is "No such file or directory".
For DVB Card Number 3, the Frontend ID is "Could not open card #3"
and Subtype is "No such file or directory".
etc.

I found one thread that suggested I set the permissions to 777 on
the /dev and /dev/dvb directory because I don't run as root. This
did not solve my problem.

My questions are:
How do I know which card ID is the newest? (I assume the
instructions above are asking for the newest card ID.)
Subtype say "No such file or directory" but I don't remember creating
a directory for the first card; is there a directory I'm suppose to
create for the second pcHDTV card?
I haven't installed any other drivers. I understand that the drivers
are already built in for this card. Right?
Any one have suggestions for me?

If you say the permissions are OK, I'm guessing that the DVB devices
for the second card do not exist. Try

$ ls -l /dev/dvb/adapter*

to see whether you have two adapter directories present.

Card's are 'usually' numbered in the order they are detected by the
system, and 'usually' this means the higher the PCI slot # (i.e. the
further away from the video card the PCI slot is), the higher the card
ID.

If it's due to the missing DVB directories I mentioned above, these
should be created automatically when the DVB module loads.

If it is not being detected by the system then I would reseat the
the case.. if that does not help try moving it to another PCI slot.

Only one directory is present. That is "adapter0".

Okay. So I only have one "adapter0" and the system is not creating
the second directory when the DVB module loads. What can I do to fix
this situation?

Note: I have removed the old working capture card and verified that
the new card DOES work when it is the only pcHDTV card in the
system. It just doesn't work when both cards are in the system.

Multiple PCHDTV cards not seen

I have a similar problem but with one pcHDTV-3000 and one pcHDTV-5500. Both work with KnoppMyth when they are alone in the system. When both are present we only see one card.

There is an error message in the boot log related to the unseen card:

ioport range could not be reserved
then later
Failed to allocate mem resource ...

As with your case, no /dev/dvb/adapter1

I was wondering if you see the same kind of problem in your boot messages?

And, does anyone have a suggestion on how to proceed?

Unfortunately, I am a NOOB to unix. My boot log in /var/logs/boot.log is empty and I don't know where else to look. Can you help me?

Here are the older threads on this issue:

http://www.gossamer-threads.com/lists/mythtv/users/295420
http://www.gossamer-threads.com/lists/mythtv/users/295503

I don't know if these procedures are the actual solution but here's what happen that resulted in getting both pcHDTV cards working.

Both pcHDTV cards were in my MythTV box but only one was working. Then last week, MythTV lost track of the one working card and would no longer record any shows. Watching shows continued to work just fine.

After quite a bit of research and futzing with the system, I decided to delete all capture cards from the system. I chose "Delete all capture cards" from option 2 in MythTV Setup. Then added "New capture card" with Card type: "DVB DTV capture card (v3.x)" and DVB Card Number: 0. This capture card became [DVB:0]. I only have one Video source, "Antenna", so I connected "[DVB:0] (DVBInput) -> Antenna". The card closest to the AGP video slot began to work.

Following the instructions at:
http://www.mythtv.org/wiki/index.php/Configuring_PCHDTV_card_for_ATSC

I changed [DVB:0] to [DVB:1]. After all, it does say "If you have multiple DVB cards you need to change the device, to the one for the newest card." However, this resulted in the card farthest from the AGP slot to work; the card closest to the AGP stopped working.

I deleted all capture cards again and started over with one capture card name [DVB:0] and the second named [DVB:1]. I connected both to the same Video source so that "[DVB:0] (DVBInput) -> Antenna" and "[DVB:1] (DVBInput) -> Antenna". This time, both cards could be seen and opened but only one card could be recorded from. MythTV thought both cards could record so would schedule multiple simultaneous recordings.

To finally get both cards open and recording, I moved one of the cards to a different slot in the computer. I deleted all capture cards, added [DVB:0] and [DVB:1], connected them to my only Video source, and everything worked!

So either the "Configuring PCHDTV card for ATSC" article is wrong or my Myth box is setup incorrectly. I don't care; I am now recording multiple reruns of shows as there is current a writer's strike going on.

Of course, it wasn't as easy nor straight forward as the procedures above. I spent many hours testing one card, then the other, then connected to physical antenna, and so on... and so on... I ran across other people with this similar problem. I hope that these instructions will help solve your problem too; and then again, you may have to just wait until your computer forgets about it's only working video card before you can proceed.
