Regarding stb6100 doc the tuning procedure should be: 1. Disable PLL (LPEN_LPEN) 2. Set-up the tuner 3. Start PLL 4. Start VCO search 5. Wait for 5 ms 6. Disable VCO search, turn off VCO search clock and disable LPF BW clock The steps 1-5 should be done in 5 steps (not less) and as I remeber I've got better result when inserting small delay between steps 1 and 2 and the delay from step 5 was set to 10ms. In stb6100.c are steps 1 and 2 done together within 1 write to stb6100 registers and this seems to be not optimal for some modulations.
