DVDR80 help please!

hi all!
oi have a dvdr80 ( b.new) and a cable pace box (2000) for ntl. i had to buy a red-eye translator so the g-link on the pillips could communicate with the ntl box. i left it on all night for it to “update” woke up this morning and on the guide plus+ i have most of the channels there now ( but not alll?) and i have another problem, that is half of the channels don’t have listings on, (even channels like itv?) Any idea why this has happened? Cheers!
