This is my first post. Sorry if it's in the wrong place. Lately my HR22 has been freezing up on playback. Seems to be happening more & more. If I just wait it will finally move on, skipping some of the program. Sometimes it won't respond to the remote when this happens. It is happening with programs recorded on different channels. I don't notice it on live tv. Is my DVR dying? The batteries in the remote are new.
