bool cDvbApi::Probe(const char *FileName)
{
  if (access(FileName, F_OK) == 0) {
     dsyslog(LOG_INFO, "probing %s", FileName);
     int f = open(FileName, O_RDONLY);
     if (f >= 0) {
        close(f);
        return true;
        }
     else if (errno != ENODEV && errno != EINVAL)
        LOG_ERROR_STR(FileName);
     }
  else if (errno != ENOENT)
     LOG_ERROR_STR(FileName);
  return false;
}

The first thing VDR does when looking for DVB devices is to check
if it can access the file /dev/ost/frontend# (# = 0, 1, 2, 3).
If such a file can be accessed, the message "probing..." is written
to the log file. So in your case the only explanation is that there
is no such file, or that it can't be accessed. I'm still in doubt 
whether is can be absolutely, positively ruled out that there is
a '-D 0' option in the call to VDR...
