since i guess you want to retrieve a single channel from this full ts, you 
have to find the right vpid/apid pair (from your channel.conf or whatever)

if replex fails again, you can try to compile this:

----------------------
/* save as ts2ts.c*/
/* compile with gcc -o ts2ts ts2ts.c*/

#include <stdio.h>
#include <unistd.h>

int main(int argc, char **argv)
{
  int pid, pid1, pid2, n;
  unsigned char buf[188];

  pid1=atoi(argv[1]);
  if ( argc >2 ) pid2=atoi(argv[2]);
  else pid2 = -1;

  fprintf(stderr,"filtering PIDS : %d %d\n",pid1,pid2);

  for (;;) {
    n=fread(buf,1,188,stdin);
    if (n==188) {
      pid = (((buf[1] & 0x1f) << 8) | buf[2]);
      if (pid1==pid || pid2==pid ) fwrite(buf,1,188,stdout);
    }
  }
}

-----------------

and run :

cat your_ts_file | ts2ts decimal_vpid decimal_apid > single_channel_ts_file

and then :
replex -i TS -t MPEG2 single_channel_ts_file > replexed_file.mpg
