Also your Media selection sizes are surprisingly the same as AVCHDCoder's ouput sizes so I thought I'd find AVCHDCalculator in your package. But I couldn't find it. So my question is: how did you do it?
Media sizes:

and output sizes ...many hours of work and much research

Sample:
Code:
...			
size = audio * Video[i_v].duracion;	
n_packets = size / (1536-head);	
over = n_packets * head;			 
media -= size;
media -= over;
	
n_packets = media / 1536;
over = n_packets * 81;					
media -= over;  									
media -= (300 * 8 * Video[i_v].frame_count);	   
	
bitrate = (int)(media / (Video[i_v].duracion * 0.9893));
....
