Oh I used to HATE that! It used to drive me NUTS when this happened. Now we don't have tv and use hulu only. Looks like the Good Wife IS on hulu. You can skip forward to the end of the show so you don't have to watch the show all over again. If that doesn't work, you can search around on youtube. Looks like some people post the tv episodes on there too. The only issue I have with using youtube is that it can get confusing b/c each video has to be like 15 minutes long. So there's "part 1, part 2..." some people write "part 1 of 4, part 2 of 4."
@ Geri - isn't American Idon on FOX? So it's not just CBS.
But yes, the DVR bugs. It's NOT just CBS (but CBS is the least-cooperating with hulu.com. ) My suggestion is just to ALWAYS set it to record the next show too. Amazing Race almost ALWAYS goes over, doesn't it? I think I had the same problem with the same show a few years back.
