a home-based network for coupling said clients to said PVR media server and for transferring said buffered television signals to said assigned clients,

wherein the system is configured for selecting a set of tuners for tuning the received signals, wherein the selected set of tuners is located within the home-based network,

wherein the selected set of tuners are coupled to storage media for buffering the signals for the assigned clients, the storage media located within the home-based network.

10. The system as set forth in claim 9 , wherein said at least one PVR media server comprises a single PVR media server comprising a plurality of tuners.

11. The system as set forth in claim 9 , wherein said at least one PVR media server comprises a plurality of tuners located in a plurality of PVR media servers.

12. The system as set forth in claim 9 , wherein said PVR media server further comprising storage medium for storing at least one television signal so as to record said television program.

14. The system as set forth in claim 12 , wherein said system further comprises software for resolving any conflicts to assign an available tuner for said television signal.

15. The system as set forth in claim 14 , further comprising software for determining whether one of said tuners is available to receive said television signal;

if so, for assigning said tuner to receive said television signal;

if not, for determining which tuners are potentially available, for querying clients assigned to said tuners potentially available to determine whether said clients desire to cancel recordation of said television program, and for assigning a tuner potentially available to receive said television signal if no clients cancel recordation of said television program.
