If you plan to perform a "Clear and Delete Everything", do it BEFORE you let the v6.3a software install. One side effect of the "C&DE" is that you'll lose your channel logos in the Now Playing List and channel banners. Those logos are only restored after a software update, so you should get them back when your DVR updates to v6.3a (although sometimes it takes a few days for them to appear after the next phone call and a reboot).
