They are ?, where did you read that ?
Ive had SkyHD from the first day it came out (literally the first day), we dont have Sky Sports but I think its well worth it for Sky Movies although the PQ isnt as good as a Blu-Ray.
I also like stuff like Stargate Atlantis, 24, Lost, Heroes, BattleStar Galactica etc etc all in HD on various channels.
Some stuff can still be very poor even though its in HD, I was watching Burn Notice on FXHD the other day and was amazed at how bad some on the PQ actually was but on the whole im pretty happy with SkyHD even at the price I paid ..... so long ago I cant even remember how much it was ...bet the wife can though
