I am trying to get my DC10+ video capture card to work on the
Linux Redhat 8.0 system I just built at home.
For an assortment of reasons, one being to prove that Linux
can do anything windows can do, I want to do my video capture
using the Linux box.
The box is a clean install of RH8.0 from the iso.org tapes and
then I ran RedHat Network to pick up about 96 meg of updates
(It is good to have DSL). I am running the linux-2.4.18-19.8.0
kernel.
Attached is the analysis I have gone through so far. Can someone
give me a suggestion on what to try next. My best clues are
at the bottom of this posting.
The install correctly identified the card and said it configured it.
The hardware browser shows it is there, shows:
ZR36057OQC Video cutting chipset
Manufacturer: Zoran Corporation
Driver: zr36067
Device: N/A
The missing device name worries me as it should be connected to
/dev/video0 (character device, major 81, minor 0). However my
actual video card also shows no device, so I am uncertain as
to whether this is serious.
lsmod shows the driver is loaded:

All accesses to /dev/video0 through 3 give:
**ERROR: [lavrec] Error opening video-device (/dev/video0): No such device
++ WARN: [lavrec] Not ready for capture (state = 0)!
/proc/pci shows that the device has been detected:
Bus 0, device 15, function 0:
Multimedia video controller: Zoran Corporation ZR36057PQC Video cutting
chipset (rev 2).
IRQ 5.
Master Capable. Latency=32. Min Gnt=2.Max Lat=16.
Non-prefetchable 32 bit memory at 0xdb101000 [0xdb101fff].
Bus 0, device 17, function 0:

IRQ 5.
Master Capable. Latency=32. Min Gnt=2.Max Lat=24.
I/O at 0xec00 [0xecff].
It is strange that it shares the IRQ with the sound card. I disabled COM2 in
the bios and then told the bios to force PCI slot 2 to use IRQ 3. It did this,
but then the sound card (on the motherboard), moved with it to IRQ 3. It seems
the BIOS thinks these should be on the same IRQ. I tried making IRQ 3 a
legacy device IRQ, but then the BIOS ignored my attempt to force the use of
IRQ 3 on the DC10+ card and went back to IRQ5. I have tried the PNP OS flag in
the BIOS in both the ON and OFF posistions, and have not noticed a difference.
