At the moment it can take as long as 5-7 seconds for me before I get both audio and video running after changing channels. About 4 seconds to get the audio, and then a couple of seconds before the video starts aswell. Is there anything I can do to speed this up, if I'm not mistaken the TV-card is an important factor, but can stuff like gfx card, CPU, memory and SSDisk speed it up aswell?
