| 24 | Firmware: |
| 25 | |
| 26 | The firmware needs to be extracted from the Windows Hauppauge HVR-1600 |
| 27 | driver, available here: |
| 28 | |
| 29 | http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip |
| 30 | |
| 31 | Unzip, then copy the following files to the firmware directory |
| 32 | and rename them as follows: |
| 33 | |
| 34 | Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw |
| 35 | Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw |
| 36 | Drivers/Driver18/hcw18mlC.rom -> v4l-cx23418-dig.fw |
