I am very confused about the current terms that are used to describe a standalone A/V recorder that records external analog/digital sources via RCA connectors to a hard drive. For a sort of explanation my cable set top records the cable signal to an internal hard drive. If it had external inputs it would do what I want. I am looking for a DVDR type device that can also record to a built in hard drive. Or a combo VCR with hard drive that allows hard drive recordings full time unless I switch the input choice. Preferably I want a HARD DRIVE recorder with external RCA inputs and outputs plus coax in/out connectors as well. With all these various units the names attached to them are not very helpful. I would appreciate a list of device names with its capabilities, connectors, and the current name attached to them. I can find a VCR/HDD combo or a DVDR/VCR combo but I no longer want to use recordable media. All advice welcome.
