Huh? You state you never had HDMI issues, but then in the next sentence you indicate that you periodically have to remove the HDMI cable and reinsert it to resolve loss of audio. That sure sounds like an HDMI issue to me, but actually what most folks are waiting on is Dolby Digital 5.1 audio via HDMI. Obviously the HDMI hardware issues (i.e. fragile connector) won't be resolved with a software update.
If thats the way to interpret it then I do have HDMI issues. I actually purchased 2 vip622 dvr's for about 1200$'s which was very painful. I don't know if the audio loss is hdmi related or is it my Pioneer PDP-5061HD.
