Not sure if your Samsung HL-R5667W is capable of digital
TVGOS reception, haven't found anything on the net that says otherwise either. What city/state do you live in, we can look up which digital channel is sending the
TVGOS data.
The DTVPal Plus will receive
TVGOS over digital signals, but you will lose the capability of receiving
HD (The
Pal Plus downconverts
HD signals and sends them to your TV via RF cables).
