Sorry, I don't have too much spare time right now.
I'm afraid you'll have to look at the code ;-)

Yes, only I-frames.

device.h:

  virtual void TrickSpeed(int Speed);
       ///< Sets the device into a mode where replay is done slower.
       ///< Every single frame shall then be displayed the given number of
       ///< times.

dvbdevice.c:

void cDvbDevice::TrickSpeed(int Speed)
{
  if (fd_video >= 0)
     CHECK(ioctl(fd_video, VIDEO_SLOWMOTION, Speed));
}
