+Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
+encoder chip:
+
+1) The only hardware currently supported is the Hauppauge HVR-1600.
+
+2) Some people have problems getting the i2c bus to work. Cause unknown.
+   The symptom is that the eeprom cannot be read and the card is
+   unusable.
+
+3) The audio from the analog tuner is mono only. Probably caused by
+   incorrect audio register information in the datasheet. We are
+   waiting for updated information from Conexant.
+
+4) VBI (raw or sliced) has not yet been implemented.
+
+5) MPEG indexing is not yet implemented.
+
+6) The driver is still a bit rough around the edges, this should
+   improve over time.
+
+
+Firmware:
+
+The firmware needs to be extracted from the Windows Hauppauge HVR-1600
+driver, available here:
+
+http://hauppauge.lightpath.net/software/install_cd/hauppauge_cd_3.4d1.zip
+
+Unzip, then copy the following files to the firmware directory
+and rename them as follows:
+
+Drivers/Driver18/hcw18apu.rom -> v4l-cx23418-apu.fw
+Drivers/Driver18/hcw18enc.rom -> v4l-cx23418-cpu.fw
