What are the criteria for the Search function on the DCX3510-M PVR and the HD Guide?
The program "Grantchester on Masterpiece" is scheduled in the HD Guide at 9:00 PM on Sunday, June 18, 2017. I found this program by scanning through the HD Guide listings after unsuccessfully searching for it with the Search Function. Entering the keyword "Masterpiece" or the keyword "Grantchester" returns zero results in the Search function yet the program with both those search terms in its title is there in the HD Guide.
The Search function is of limited value if it cannot find program titles that are in the HD Guide.
