There is no doubt it has been improved as the software is updated, however mistakes have been made that quite rightly attract criticism ie the lack of info button on the remote to name just one.
For accurate information this forum is the best place to seek advice and help, especially if it is deemed urgent. Having just had a quick glance at other places they either have incorrect or misleading info most of the time, and have members who do not even own a unit posting absolute nonsense.
I would not recommend reading early reviews, they are based on outdated info from owners using early iterations of software.
