By default, Windows Media Center places the live TV buffer in the Recorded TV folder. Depending on what physical drive you are using for Recorded TV, the path to the Recorded TV folder will vary. If you are using the main OS drive, the default Recorded TV folder is C:\Users\Public\Recorded TV\. If you are using a secondary drive, the default path will be <drive letter>:\Recorded TV\. In both cases, the live TV buffer will be stored in a hidden folder named TempRec. To change the location of the Live TV buffer, you can create a symbolic link to a new location by following these steps:
Important note about using a Solid State Drive (SSD) for the live TV buffer: Solid State Drives have a finite lifespan that is directly related to the amount of data that is written to the drive. Live TV buffering/recording requires writing significant amounts of data, far more than any other normal activity on a home theater PC. Using an SSD for the live TV buffer may significantly decrease the lifespan of the drive. Additionally, there is no advantage to using an SSD for the live TV buffer instead of a hard drive unless you are already overworking your hard drive. Before deciding to use an SSD for live TV buffering, evaluate how much data your drive is rated to write, and compare that to how much data is required to be written to sustain your TV viewing habits.

Question: I have several eSATA towers that I use for recording, but if I want the live tv buffer on an internal drive, do I have to make a link in each tower to point to an internal drive so when I switch recording locations the buffer will remain in the same place?
