Is there any such thing as a universal DVR?I mean plug in the coaxial cable and it will work with any cable service.

TiVo, or roll your own.
Well there are "universal" remote control devices that claim to work with any DVR or similar home entertainment devices: one device to control many....

As for working with any cable service you still will need the cable box from the service provider to connect to the DVR. Or a combination device via your provider that serves both functions. I.e., Service provider coax --------> Cable box --------->DVR ---------->TV.

Google "DVR cable box connection diagram" and you will find many connection options.

However, the DVR/device being connected to the service provider's incoming cable will need to be registered with the provider as a legitimate device to receive service. Otherwise you will be breaking the law.
