Well, I haven't been able to try the guide while watching live tv, 
probably due to this error.
For now I'm just using the program guide you can find in the menu.
(However, getting the live guide to work would be nice, I have already 
found a mythtv ticket here which apparently solves THAT issue by 
disabling deinterlacing, as you said: 
http://svn.mythtv.org/trac/ticket/3986 )

Anyhoo, I do believe my problem is about the channel icons. It's similar 
to this thread:
http://www.mythtvtalk.com/forum/archive/o_t/t_2607

I have looked at the full log and have found that it directly downloads 
the channel file, which takes a few microseconds.
If it has done this once, it doesn't download the files again. But it 
still takes a lot of time.
When I'm in a section of the guide, with channels with no icons, it's as 
smooth as it should be.

I know I can just remove the channel icons (even though a 
mythfilldatabase would constantly re-add them)
I still think it's important to fix it.
