** number of PID that can be blocked or passed, for example: 10 services, each have 6 PID's so there are 60 individual PID's plus tables (like
PAT, SDT, NIT, EIT etc.) so all in all ~70 PID's
1) if you enable 6 services there will be 36 individual PID's + 4 PID's for tables (40 PID's to pass). In this case filter works in "Pass All" mode
while blocking remaining 70-40=30 PID's.
2) if you enable 4 services there will be 24 individual PID's + 4 PID's for tables (28 PID's to pass). In this case filter works in "Block All" mode
while passing those 28 PID's.
3) if you select 5 services there will be 30 individual PID's + 4 PID's for tables (34 PID's to pass). In this case the "Error to many PID's" is shown,
because module has to pass 34 PID's in Blocking mode or block 70-34=36 PID's in Passing mode and the limit is 31 in either mode.
