There are 2 different things: 1) the value of seq: old driver used a table. Full autosearch (i.e. INVERSION_AUTO, TRANSMISSION_AUTO, GUARD_AUTO) = 11. No autosearch = 0 new driver. Autosearch = 7 (7 is not present in the old table), No autosearch = 0. (In the old table, autosearch for TRANSMISSION & GUARD corresponds to 6) 2) how seq is written to the register 5 OLD DRIVER : (seq & 0x0f) << 4) | (1 << 8) line 286 here http://linuxtv.org/hg/v4l-dvb?f=c8f23ba912d8;file=linux/drivers/media/dvb/frontends/dib3000mc.c;style=gitweb check macro DIB3000MC_SEQ_TPS(seq,1) line 71 here http://linuxtv.org/hg/v4l-dvb?f=1bd99532ee0f;file=linux/drivers/media/dvb/frontends/dib3000mc_priv.h;style=gitweb NEW DRIVER : seq directly line 502 in the current version of dib3000mc.c As you said the value 11 does inversion search as well (which might be not needed), but I think the important issue is the second. Hope I've explained in a decent way. I have a question: if the board can do autotune, why do we bother with setting the right parameters?

Please give me some time to understand the solution. I think only one of the two things should fix it (putting seq to 11 also searches for inversion which is not necessary). Anyway, thanks for digging out this thing. Patrick.
