Annoying DVR mishaps

So when I got home last night, my DVR was in the process of taping both the season 3 premiere of Shameless and the second installment of Generation Kill. I decided to start with Shameless and then proceed to Generation Kill afterwards so I clicked on the button to start Shameless from the beginning. When I got about 45 minutes in, the recording shut off all of a sudden and I realized that when I started from the beginning, the DVR glitched and stopped taping. It will be on again this week so I can see the last 15 minutes on Thursday - not that I can't guess how it will turn out. Now that both James McAvoy and his wife have left the show, I'm a little afraid that it has nowhere to go. Last night was yet another variation on the let's come up with a comic scheme to avoid being found out by social services plot and it had a ho-hum quality to it. Nevertheless, it was very frustrating to get so close to the end and yet be cut off so abruptly! Had I realized it had stopped taping I wouldn't even have started it and would have just waited to see the whole thing on Thursday. Argh. Has this happened to anyone else?
