Hi all,
in attachment 2 new patches for DVB-T drivers in kernel 3.1.0.

The first one fixes SNR display in Enigma2 (and also with Kaffeine under Ubuntu) for the PCTV 290e DVB-T/T2 stick.
The original driver outputs the SNR as dBx10; this value is now capped to a max SNR value (dependent on the delivery system and modulation type) and then scaled to the full range 0-65536 that is displayed by the coloured bar in Enigma2. The result is very nice.

The second patch is a minor fix to the xc3028 tuner that makes possible to tune VHF channels.
