+/* ivtv knows several distinct output modes: MPEG streaming,
+   YUV streaming, YUV updates through user DMA and the passthrough
+   mode.
+
+   In order to clearly tell the driver that we are in user DMA
+   YUV mode you need to call IVTV_IOC_DMA_FRAME with y_source == NULL
+   first (althrough if you don't then the first time
+   DMA_FRAME is called the mode switch is done automatically).
+
+   When you close the file handle the user DMA mode is exited again.
+
+   While in one mode, you cannot use another mode (EBUSY is returned).
+
+   All this means that if you want to change the YUV interlacing
+   for the user DMA YUV mode you first need to do call IVTV_IOC_DMA_FRAME
+   with y_source == NULL before you can set the correct format using
+   VIDIOC_S_FMT.
+
+   Eventually all this should be replaced with a proper V4L2 API,
+   but for now we have to do it this way. */
