I want to know the answer to the following question:
Did all AV receivers carry the demodulator circuits necessary for LaserDiscs, or only high-end models?
All the background I'm provided with is that "Although DVD players were capable of playing Dolby Digital tracks, the signal out of DVD player were not in a modulated form and not compatible with the inputs designed for LaserDisc AC-3.". Is that enough to answer the question?
Answer: no
