AFAIK Virgin didn't hack away at the RoB episodes, with the exception of the Christmas specials, though somebody chopped out most of the "see you next week" bits but that was before Virgin came along..

There have been cuts for as long as Challenge [TV] has been a thing. The Britbox versions represent the first time they've been available in the UK in their complete form since Channel 4 stopped airing it.

Someone mentioned here that there is a way to watch Challenge content on-demand, but i couldn’t find it anywhere in the Sky Q “catch up tv” section, despite it heing a sky channel, nor in the tv guide via the “available now” section [which wasn’t displayed]. I don’t really know why Sky don’t just provide these as downloads considering it probably costs them very little to put out these episodes, and broadcasting just one episode per series makes little sense.

That area was pretty well populated a few years ago, but last time I checked (on Now) it was down to just a few recently showed episodes of Pointless. I guess Sky concluded it wasn't really adding any value to their overall on demand offer.
