[linux-dvb] Re: AverTV DVB-T un-viewable QAM_64 channels (QAM_16work perfectly) ...massive noise

[Rick Hamnett <rick@packetoverdose.com>]

Hi thanks for your input

The thing is the channels even QAM_64 work ok on windows, plus my 
flatmate has a proper digital freeview tvbox and he gets perfect 
reception too, tried it on my aerial socket too

If i bought a cheap happuage nova-t pci card ..... i think it doesnt 
come with a remote....but i want a remote....what can i do?

Thanks
Rick
