Hans Verkuil 1c1e45d17b 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!
