Do you have the HD add on? If not please try changing the default download preference from HD to SD in
Main Menu > Settings > Setup > Preferences

If you do have the HD add on or the above does not fix the issue you will have to call Sky. They will then try to refresh the viewing card which sometimes needs a couple of attempts. This link explains more: https://www.sky.com/help/articles/call-to-upgrade-downloading-on-demand#q-help-articles.
