Wooshman/Alfadaz,
I switched the region to NI and did a NIT Scan - it did not do anything. I changed it back to ROI & did a NIT scan - no change.
Kiddac, I did as you suggested & it worked. Did a software update (28 updates) and it is still filling the screen - good news.
The interesting thing (to a nerd like me) is that the icon on TV3 is showing 4:3 (even for Euro 16 coverage - should be 16:9), whereas, all the other channels are showing 16:9.....
I will wait for the final version of Wooshbuild v4 and flash it from scratch, hopefully, everything will be back to normal.
Thanks for the advice guys.
Mike
