RayJ sounds like you are in worse position than me; at least by me reverting to a previous software release (5.01), I have a more stable version of software.
I suspect that if you reverted to the previous software, you would now get version 6.01 (which in my opinion is just as bad; this was released around mid December).
In case you do not know how to revert to the previous software
Menu > Setup > Help
Press the green button, then yellow button, then green button. Follow on screen instructions.
Unfortunately topuptv answer to virtually EVERYTHING is to reboot! If only the software was more robust.
Just hope the software developers are watching (whoever you are)!
As a matter of interest, does your box 'freeze' for a couple of minutes shortly after switching on, such that it ignores all signals from the remote control? Presumably the software is doing some housekeeping procedures or other. I find this extremely frustrating. Surely such events could be performed on switching off?
