Having previously had Virgin Media (and currently have Sky) the BT Youview software really is terrible:
-Recorded an FA cup game from last week. Game went to extra time. Was the Youview/BT software smart enough to realise this and continue recording? No, it cut the programme early.
-Go to play a recording and sometimes says "recording unavailable" (even though it did record)
-Was recording matches on two channels once. I turned the box on, thinking they had finished. Because BT don't allow recording two channels and watching a third, it turned to one of the two recording matches (spoiling the result). In contrast sky will take you to a "dummy" channel, rather than forcing you to watch the recording channel.
-Recorded a programme (on the BT box hard drive). Went to play the recording and it said "Internet unavailable", even though the current channel was playing (so internet was fine) and a recording should not require the internet, it's downloaded to the hard drive!
I would be embarassed if I was a Youview software developer
