Hello Klaus,

thanks for the answer.

With following lines (only for test and with plain vdr 1.3.35):

  bool NTSC = false;
  isyslog("skinelchi: ask for NTSC and OSD");
  if (cDevice::PrimaryDevice()->GetVideoSystem() == vsNTSC)
    NTSC = true;
  isyslog("skinelchi: %s", NTSC ? "NTSC" : "PAL");
  bool PAL = false;
  if (cDevice::PrimaryDevice()->GetVideoSystem() == vsPAL)
    PAL = true;
  isyslog("skinelchi: %s", PAL ? "PAL" : "NTSC");
  if (fd_video >= 0) {
/*  fd_video is set before with this:
    char *dev = NULL;
    asprintf(&dev, DEV_DVB_VIDEO, cDevice::PrimaryDevice()->CardIndex(), 0);
    fd_video = open(dev, O_RDONLY | O_NONBLOCK);
    oldbm = NULL;
    free(dev);*/
    if (ioctl(fd_video, VIDEO_GET_SIZE, &vs) == 0) {
        if (vs.h == 480 || vs.h == 240)
     PAL = false;
 }
    }
  isyslog("skinelchi: %s", PAL ? "PAL" : "NTSC");

i get the following lines after messages from mplayer in user.log

looks like the filedescriptor "fd_video" will not be valid, but with vs.h =
480 and if i ask the driver for myself it works.
