Alas, my DVR won't save me tonight

The networks are cold, heartless bastards.They want us to watch their shows in order to grab ratings and ad revenue; yet, they mess around with their schedules so much that it's frustrating. Eventually, it gets hard for us not to pick up the damn television and throw it out the window. Well, more like get a few people to pick it up and throw it out of the front door. Come on, those flat screens are heavy!
You're probably wondering what I'm ranting about, aren't you? Well, it involves tonight's primetime schedule during the 8 pm time slot. On CBS, we have The Big Bang Theory and How I Met Your Mother, while FOX has a new House. The 100th episode of House, to be exact. Now, this wouldn't normally be an issue, since I could watch one network and record the other on my DVR. But, NBC decided to bring back Chuck tonight, as well.This has left me in a bit of a conundrum, you see. My DVR has the ability to record only two shows at a time. Since I have only one of these devices, I had to pick between these shows to determine which ones to record. As I really like the shows on all three networks, this was a hard decision to make. Especially since I am in no way interested in coughing up more money to my cable provider for another DVR box.
Unfortunately, Chuck lost out in this battle. While I enjoy the show very much, I'm a bigger fan of BBT and House, and would not want to miss them. If there's any consolation, it's that I can watch episodes of Chuck online. In addition, I know that this won't always be the way it is for the rest of the season. Come March, I can see a little more flexibility in what I record as these shows come and go with new episodes.
I'd be very interested to know if you are encountering the same dilemma I have this Monday night (Joel faced a similar situation earlier in the season, before House was thrown in to complicate things further). Not only for the 8 pm hour, mind you. I know that there's going to be a casualty for some people at 9 pm as Two and a Half Men, Heroes and 24 go head-to-head-to-head. What have you decided to sacrifice in order to watch or record your other programs? Or, do you have the necessary equipment to record all of the programs at one time?
