I have had all of these problems (channel icons, memory, playback
profile, ...) and have fixed them all, but the guide is still painfully
slow on my box.

I've deleted all the channel icons, increased the memory, rarely use the
guide in livetv (always the regular one in the menu) but it's still slow
as hell.

Maybe it's because I have 2000 channels, you say?

I've "disabled" 1800 channels (made them invisible) but that didn't sole
a whole lot.
