Necro'ing this thread because I just discovered this issue. While watching recordings of The Biggest Loser followed by the Voice on Tuesday (both NBC) , my wife was upset that the the "scenes from next week" at the end of Biggest Loser were cut off early. I expected them to be at the beginning of the Voice recording, but alas, that recording started right off with the opening for the Voice.
Now, my workaround is to futz with the timers to force Biggest Loser to record an extra 2 minutes, but in doing so this forces The Voice to record on TV1 instead of TV2. Not a huge deal but it is inconvenient and unnecessary.
We're going to have a much bigger problem on Thursdays, when the wife records Grey's Anatomy/Private Practice (both ABC) and I record Awake (NBC) at the same time as Private Practice. There is going to be no way at all to extend the recording of Grey's Anatomy, and if it doesn't pick up the preview of next week I'm going to hear about it.
So I need to either go out and buy an OTA antenna, which I'd rather not do (but I'll take recommendations), or Dish needs to fix it so 1 tuner can record more than one thing on the same channel. This is obviously quite possible - DirecTV even defaults to picking up a small buffer on either end of its recordings. Isn't there anything Dish can do to fix this? The Dual Mode setup is limiting enough without this issue. I love saving the money, but come on.
