The hvr950 is fully supported in the following tree:


Beware, that installing this tree will break all devices that use non-xceive
tuners.  ...yes, that means that pvrusb2 is in fact broken in this tree.

The original author of the em28xx / em2880-dvb / xc3028 driver has pulled his
development trees away from linuxtv.org -- Although I added the hvr950 support
to these drivers, I cannot offer any tech support.

This device family is not supported by the mainline kernel, nor will it be
merged anytime soon.

TO ROGER:  The selling point of the hvr950 is atsc support.  Yes, it is capable
of raw analog capture, but the device does not have an mpeg encoder.  It works
fine for watching live analog tv, or digital tv, but it is not meant for
recording analog.  digital recordings, otoh, is a different story.
