Thanks for the update. That is interesting because I know the YouView issue caused a lot of problems and confusion. Sounds like Sony have listened and improved things. Being able to record one channel while watching another means you have a dual tuner model, something I can do on mine.
The only other practical issue I've encountered (and maybe this is fixed as well) is that when you set it to record an event it says for example that 20Gb space is needed and yet when you look at space remaining after it has recorded it reports only a small amount of space has been used (say 1Gb). On the earlier models that is a glitch and the figure reported remaining is correct, the space it says it needs to record is incorrect.
Enjoy.
