I've just posted this on hummy.org and had no response but at least now I know it's not just me!
On Friday on ITV 1 Emmerdale and Corrie recorded for only a couple of minutes each - and that was just the adverts before they started. I put it down to "just one of those annoying glitches" but again yesterday (Monday) Corrie only recorded for 30 seconds.
I even set ITV1+1 to record just in case it happened again and it didn't even record the first episode of Corrie but just the second and this was in full.
On Friday and last night the second episodes of Corrie were fine.
My recordings were individually set and weren't series linked like yours.
