Installed FC4, followed Jarod Wilsons guide, even tho its for FC3.
Since FC4 is using a 2.12 kernel, all I needed to do as root was:
Checked dmesg and saw:
cx2388x dvb driver version 0.0.4 loaded
ACPI: PCI Interrupt 0000:01:07.2[A] -> Link [LNK1] -> GSI 3 (level, low)
-> IRQ 3
cx88/2: found at 0000:01:07.2, rev: 5, irq: 3, latency: 32, mmio:
cx88/2: cx2388x based dvb card
DVB: registering new adapter (cx88).
DVB: registering frontend 1 (pcHDTV HD3000 HDTV)...
Checked the permissions on /dev/dvb/adapter1 (as adapter0 is my air2pc
ll -h /dev/dvb/adapter1/
crwxrwxrwx 1 root root 212, 68 Jul 23 11:44 demux0
crwxrwxrwx 1 root root 212, 69 Jul 23 11:44 dvr0
crwxrwxrwx 1 root root 212, 67 Jul 23 11:44 frontend0
crwxrwxrwx 1 root root 212, 71 Jul 23 11:44 net0
All was good on the permissions (note, you may need to modify the
permissions on the dev if you dont have rw access to it, and it may not
survive a reboot, so youll have to add it to your init scripts)
Fired up mythtv-setup and was able to config the pchdtv3k card with no
P.S. Oh yeah, this is for OTA HD broadcasts and I CAN watch and record
off the pchdtv3k card.
