This update rolled on to my HR34 a few days ago. It's running better overall but I noticed that smart search no longer has th Far In Advance functionality. This really sucks for me because I use it to search for shows all that time that aren't in my usual 2 week guide window.
You might want to look for a few other items as I should be there for items that have data. DIRECTV doesn't get Far in Advance data for all programs (though I suspect there are more and more all the time.) So if you don't see something, that more likely means DIRECTV doesn't have the data yet.
