This is very useful, thank you very much! Thing is I was merely using the sound from the DAC (not actually CAPTUREing sound) but I nowhere set the audio carrier freqs, although they were in my saa.h from the beginning: #define FREQ_SND_PAL_B_G 5.5 // Sound carrier frequency, MHz (not used) #define FREQ_SND_PAL_I 6.0 #define FREQ_SND_PAL_D_K_L 6.5 #define FREQ_SND_NTSC 4.5 That explains your 6.5 too I reckon :) Cheers, Dan
