V4L/DVB (7786): cx18: new driver for the Conexant CX23418 MPEG encoder chip
Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from Conexant for their support. I am in particular thankful to Hauppauge since without their help this driver would not exist. It should also be noted that Steve did the work to get the DVB part up and running. Thank you!

13 This is a video4linux driver for Conexant cx23418 based
14 PCI combo video recorder devices.
15
16 This is used in devices such as the Hauppauge HVR-1600
17 cards.
18
19 To compile this driver as a module, choose M here: the
20 module will be called cx18.
