Lately the closed captioning on my HR-44 has been getting erratic. Some lines displayed just fine, others in the same broadcast just didn't show up. At first I blamed it on poor captioning in the source material, but it didn't seem to be limited to any one channel or group of channels. It started as a minor irritation, but began to happen with greater and greater frequency to the point where it was failing to display about every other line of text. My hearing isn't all that good and I rely heavily on CC. Much to my amazement, doing a CLEARMYBOX search seems to have restored my CC to proper operation. Thought I'd pass this on in case it helps someone else with the same problem.
