That is the only thought that I had based on previous posts that I'd seen.  It doesn't jive though b/c nothing has changed as far as the location of the icons (or the DB) and there are some icons showing up.  I never had icons populated for all channels anyway, but I think that the ones that I had are showing up in the EPG.  

In addition sometimes when I do a PAGEUP or PAGEDN, it will actually move the channels column (on the left) and then there'll be a long pause before it updates the actual guide data block. Although in general, any action is slow.
