Earlier tonight I was fast searching 5HD and it seemed faster than before, so i checked the system info diagnostics and it appears that they have
switched to H.264(Mpeg4) Video. I checked some other channels and BBC 2hd, Universal hd, itvBe hd, Film 4hd and BT Sport 3 have switched also. While this is a good thing I have found the 2x search or 30 sec skip is now too fast !.
