EFF:

Today, you can use any device you like with your television: VCR, TiVo, DVD recorder, home theater receiver, or a PC combining these functions and more. A year from now, when the FCC’s broadcast flag mandate [PDF] takes effect, some of those capabilities will be forbidden.
Responding to pressure from Hollywood, the FCC has adopted a rule requiring future digital television (DTV) tuners to include “content protection” (aka DRM) technologies. Starting next year, all makers of HDTV receivers must build their devices to watch for a broadcast “flag” embedded in programs by copyright holders. When it comes to digital recording, it’ll be Hollywood’s DRM way or the highway. Want to burn that recording digitally to a DVD to save hard drive space? Sorry, the DRM lock-box won’t allow it. How about sending it over your home network to another TV? Not unless you rip out your existing network and replace it with DRMd routers. Kind of defeats the purpose of getting a high definition digital signal, doesn’t it?
