Re: Afatech AF9015 & dual tuner - dual_mode B.R.O.K.E.N.

[Antti Palosaari <crope@iki.fi>]

Moikka Mauro et all,

I will NACK this.

Surely it is not proper solution. And after all, I haven't got any other 
reports there is such problem. AF9015 is probably most common DVB-T USB 
hardware today and if there is major problems I am the first person got 
reports.

regards,
Antti
