I bet you are using configuration file:

     690         case 'c':
     691             psz_conf_file = optarg;
     692             /*
     693              * When configuration file is used it is reasonable to assume that
     694              * services may be added/removed. If b_select_pmts is not set dvblast
     695              * is unable to start streaming newly added services in the config.
     696              */
     697             b_select_pmts = 1;
     698             break;

I have added this to turn on -w (--select-pmts set a PID filter on all PMTs)
option because otherwise when using config file there were problems.

Just remove b_select_pmts = 1 from config file case 'c' and you'll be fine
as long as no dynamic reconfiguration is required.
