The episode guide below shows the episodes as they aired with all the revisited versions also included . The DVD releases slightly reorder some of the episodes in each series and instead of the full revisited shows they simply have the ten minutes of footage that differs from the original broadcast included for the episodes on the disc . </P> <Table> <Tr> <Th_colspan="2"> Series </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> <Th> Average viewers (millions) </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 29 April 1999 (1999 - 04 - 29) </Td> <Td> 24 June 1999 (1999 - 06 - 24) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 17 </Td> <Td_colspan="1"> 17 July 2001 (2001 - 07 - 17) </Td> <Td> 1 October 2002 (2002 - 10 - 01) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 12 </Td> <Td_colspan="1"> 12 February 2003 (2003 - 02 - 12) </Td> <Td> 29 October 2003 (2003 - 10 - 29) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 21 January 2004 (2004 - 01 - 21) </Td> <Td> 10 March 2004 (2004 - 03 - 10) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 5 </Td> <Td_colspan="2"> 11 </Td> <Td_colspan="1"> 6 April 2005 (2005 - 04 - 06) </Td> <Td> 16 November 2005 (2005 - 11 - 16) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 6 </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 5 April 2006 (2006 - 04 - 05) </Td> <Td> 23 May 2006 (2006 - 05 - 23) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 7 </Td> <Td_colspan="2"> 12 </Td> <Td_colspan="1"> 28 February 2007 (2007 - 02 - 28) </Td> <Td> 16 May 2007 (2007 - 05 - 16) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 8 </Td> <Td_colspan="2"> 12 </Td> <Td_colspan="1"> 16 January 2008 (2008 - 01 - 16) </Td> <Td> 2 April 2008 (2008 - 04 - 02) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 9 </Td> <Td_colspan="2"> 13 </Td> <Td_colspan="1"> 28 January 2009 (2009 - 01 - 28) </Td> <Td> 29 April 2009 (2009 - 04 - 29) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 10 </Td> <Td_colspan="2"> 14 </Td> <Td_colspan="1"> 15 September 2010 (2010 - 09 - 15) </Td> <Td> 15 December 2010 (2010 - 12 - 15) </Td> <Td> 2.85 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 11 </Td> <Td_colspan="2"> 12 </Td> <Td_colspan="1"> 14 September 2011 (2011 - 09 - 14) </Td> <Td> 30 November 2011 (2011 - 11 - 30) </Td> <Td> 2.71 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 12 </Td> <Td_colspan="2"> 12 </Td> <Td_colspan="1"> 12 September 2012 (2012 - 09 - 12) </Td> <Td> 5 December 2012 (2012 - 12 - 05) </Td> <Td> 2.67 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 13 </Td> <Td_colspan="2"> 11 </Td> <Td_colspan="1"> 4 September 2013 (2013 - 09 - 04) </Td> <Td> 13 November 2013 (2013 - 11 - 13) </Td> <Td> 2.66 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 14 </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 3 September 2014 (2014 - 09 - 03) </Td> <Td> 5 November 2014 (2014 - 11 - 05) </Td> <Td> 1.92 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 15 </Td> <Td_colspan="2"> </Td> <Td_colspan="1"> 9 July 2015 (2015 - 07 - 09) </Td> <Td> 30 July 2015 (2015 - 07 - 30) </Td> <Td> 1.12 </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 16 </Td> <Td_colspan="2"> 9 </Td> <Td_colspan="1"> 9 September 2015 (2015 - 09 - 09) </Td> <Td> 13 November 2015 (2015 - 11 - 13) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 17 </Td> <Td_colspan="2"> 8 </Td> <Td_colspan="1"> 21 September 2016 (2016 - 09 - 21) </Td> <Td> 17 November 2016 (2016 - 11 - 17) </Td> <Td> TBA </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 18 </Td> <Td_colspan="2"> 9 </Td> <Td_colspan="1"> 30 May 2017 (2017 - 05 - 30) </Td> <Td> 1 November 2017 (2017 - 11 - 01) </Td> <Td> TBA </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Series </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> <Th> Average viewers (millions) </Th> </Tr>
