Advertisements My TiVo HD started doing this a few weeks ago. I got it new at the end of May, and am using it with one M card, no HDMI cables, and an external WD hard drive. I don't record HD (so why did I get an HD? My cable company switched to all digital around the first of July, so I would have had to use a cable box with my Series 2. I (foolishly) thought upgrading to an HD would be easier), and I've seen the freezing when not recording, recording on one channel, and recording on two channels. Restarting when not recording fixed it for a while, but if I'm recording I don't want to restart and interrupt the recording. With the ridiculously loose eSATA connector, the slow menu transitions, the lack of autorepeat half the time, the random jumps after fast-forward and rewind, and now the freezing, I'm regretting ever buying the HD. My Series 2 worked great, I basically loathe my HD.
