There's broadly 2 categories of OnDemand programmes.
"CatchUp" - recently broadcast programmes, typically the last 30days, Inclusive on all packages
"BoxSets" - typically complete and/or past series, only inclusive on XL/Full-House/Maxit
ITV is one of the awkward examples at the moment, with some overlap. Episode 1 of a 6 or 8-part drama is broadcast, and they release the complete series on boxset. Meanwhile, the past 30days worth of episodes (however many that is at any given time) are available as "CatchUp"
