Setup my lovely box yesterday. Great picture, loads of channels. I had a problem configuring the Tenda W150M so hard wired it, worked great. Sorted Tenda this morning, but now have no picture. Channel list there ok. but on toolbar (I am assuming these are the tuners) top one (A?) reads 0% bottom one green 99%. I should be able to watch even if I can't record other lnb input? I've even tried swapping over but it stays the same eg top 0% bottom 99% help please. ?-(
