Manu,

I'd appreciate it if you would NOT post private email threads to a public mailing list.

(haven't we gone down this road before?)

Max got the tda18271 driver working on his device -- a typo was identified that had prevented DVB-T / DMB-T tuning from working.

The fix has already been applied to the master repository:

tda18271: fix typo in RF tracking filter calibration

From: Michael Krufky <mkrufky at linuxtv dot org>

We want to set bits 1 & 2 on easy programming byte 4, not extended byte 4.

Thanks to David Wong for pointing this out.
