Problem with listings data download

[fat mike <punkrockisdead@xxxxxxxxx>]

Hi there,

I've just started trying to use your site for downloading XMLTV data,
and for some reason even though I've specified that I want data for all
the available channels I only get data for 10.  Here's the URL I
am using to get the data with:

http://www.bleb.org/tv/data/listings?format=XMLTV&file=zip&channels=bbc1,bbc2,itv1,ch4,five,abc1,bbc1_n_ireland,bbc1_scotland,bbc1_wales,bbc2_n_ireland,bbc2_scotland,bbc2_wales,bbc3,bbc4,bbc7,bbc_6music,bbc_news24,bbc_parliament,bbc_radio1,bbc_radio1_xtra,bbc_radio2,bbc_radio3,bbc_radio4,bbc_radio5_live,bbc_radio5_live_sports_extra,bbc_radio_scotland,boomerang,bravo,british_eurosport,cartoon_network,cbbc,cbeebies,challenge,discovery,discovery_kids,disney,e4,film_four,ftn,itv2,itv3,living_tv,men_and_motors,more4,mtv,nick_junior,nickelodeon,oneword,paramount,paramount2,s4c,scifi,sky_cinema1,sky_cinema2,sky_movies1,sky_movies2,sky_movies3,sky_movies4,sky_movies5,sky_movies6,sky_movies7,sky_movies8,sky_movies9,sky_movies_cinema,sky_movies_cinema2,sky_one,sky_one_mix,sky_sports1,sky_sports2,sky_sports3,sky_sports_news,sky_sports_xtra,sky_travel,tcm,uk_bright_ideas,uk_drama,uk_gold,uk_history,uk_style,uktv_documentary,uktv_people&days=2

When I get the zip it only contains the following 10 channel definitions though:

  <channel id="south.bbc1.bbc.co.uk">
    <display-name>BBC 1</display-name>
  </channel>
  <channel id="south.bbc2.bbc.co.uk">
    <display-name>BBC 2</display-name>
  </channel>
  <channel id="itv1.itv.co.uk">
    <display-name>ITV 1</display-name>
  </channel>
  <channel id="channel4.com">
    <display-name>Channel 4</display-name>
  </channel>
  <channel id="channel5.co.uk">
    <display-name>Five</display-name>
  </channel>
  <channel id="abc1">
    <display-name>Abc 1</display-name>
  </channel>
  <channel id="bbc1_n_ireland">
    <display-name>BBC 1 N Ireland</display-name>
  </channel>
  <channel id="bbc1_scotland">
    <display-name>BBC 1 Scotland</display-name>
  </channel>
  <channel id="bbc1_wales">
    <display-name>BBC 1 Wales</display-name>
  </channel>
  <channel id="bbc2_n_ireland">
    <display-name>BBC 2 N Ireland</display-name>
  </channel>

Is there something I'm doing wrong, or am I not understanding how the CGI request works?

Thanks.
