V4L/DVB (4228a): pvrusb2 to kernel 2.6.18
Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner.
The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded
cx23416 hardware MPEG2 encoder. There are two major variants of this
device; this driver handles both. Any V4L2 application which
understands MPEG2 video stream data should be able to work with this
device.
