Cleaning a movie dvd
You're kidding. Virtually everyone connects their DVD
through a direct video input.
In fact, what DVD players have RF output?
I checked a Sony DVP-S7000 (one of the first, if not the first, DVD
players). It has no RF output.
At the time DVD players were introduced, many TVs had direct inputs. I don't
know what percentage of DVD players have or had modulators.
