I've had some trouble with my amstrad box recently ( hey, who hasn't! ). Yesterday i did a full system reset and it made the system to:- Model: A20B005 Version: 4F2001 OS: 1.31B00 EPG: sky+4.10.c On another page, I read about the power off - hold "backup" in for a few with power on, until the lights come on the front ( several seconds ). This forces another download of updates apparently. Well, just so you know - my model has now changed to A20B015. Don't know how important this is, but as i get the sound / visual issues I'm hoping the is another step closer to resolution.
