[linux-dvb] WinTV-NOVA-TD & low power muxes

[Patrick Boettcher]

Hi Greg,

Do you have the possibility to try the device with the Hauppauge Windows 
driver?

The linux driver is maybe not configuring the device optimally, because it 
is more generic, whereas the manufacturer's driver is specifically for 
this particular device.

There have been some updates some time ago to improve the sensitivity. Can 
you try a more recent driver (v4l-dvb from hg or 2.6.25).

THe reported SNR of zero is expected: the driver does not set the 
indicator to something useful.

Patrick.
