NBC is going to rerun it at 12:30am ET Monday morning. I can understand not having a DVR. I still have 3 working VCRs. But, I'm surprised you don't have some kind of recording capability. Recording television has been common since the early 80s.
Find it on YouTube a day later. It will usually be broken into bits because people sometimes can't upload any videos over 15 minutes long.
You can always ask a grind to record it for you. Or you can watch it on the interntet/ phone on certain websites. Like the channel four news, Hulu.com, YouTube, and much more.
~hope this helps
Buy a DVR
I have work so I'm going to miss it. Wah. Any chance there will be a rerun???
