Sky stream playback programmes keep jumping back

[Marg13]

When I watch sky sports on playlist the programme keeps jumping back do that I have to keep watching same thing over and over again

if I try to fast forward past this it, it just jumps back again in few seconds

I have a similar problem, watching TNT Sport rugby (e.g. the Autumn Internationals) on Playlist. Every time I clear the half time and break, the stream jumps back ~30 mins. The issue is reproducible and consistent: something is broken in Sky Stream when playing recorded sports.
