I just got the HR20-100 yesterday. I tried to set up some of my series recordings, and have a situation that doesn't make sense to me. I set up American Idol to record as a series link by finding last night's episode in the guide and pressing record twice. Got the symbol that shows the series link was set up (the R in the circle with the )) to the right). I see future recordings in the To Do list, no problem. I went to do this same thing this morning with Lost, and it gives me the same R symbol that indicates a series link, but the future Lost episodes are not appearing in the To Do list. Those future episodes DO appear in the guide, but they are not set to record. I tried doing First Run only or Both, but nothing changes. I moved the priority for Lost to #1, still nothing changes. Is this a known issue, and is there a workaround/fix (other than setting up a manual record)? Why would one show work and another wouldn't? I saw a similar issue someone was having w/NBC Nightly News, but I think his is working now. Thanks.
