If a TV has two RCA connectors for audio, then that's almost certainly NOT
SPDIF. SPDIF is a digital protocol that usually employs either ONE RCA
connector or an optical connector. IMHO, the big advantage of SPDIF over
traditional analog audio is that it permits transmission of 5.1 surround
sound (and other multichannel formats) over a single cable. Unless your TV
has a built-in 5.1 decoder and connectors for extra speakers to make use of
this, there'd be little point to feeding it an SPDIF signal.
