Hi,
Is there a way to make the TV/H6500/ switch faster between DVB-C channels. Sometimes it takes 1-2sec., but sometimes a ?missing CI card etc?? message appears on the screen and it take 5-10sec. to open the channel.
P.S. I?m using oscam, but I noticed the TV behaves the same way also with a CI and card in it.
