Now to add about the R’ Miller comment.
I really think this has to be an opinion rather than fact because otherwise it brings up a lot of problems.
When he says anyone who has a TV does he mean that it is the act of owning the TV thats the issue? So If my neighbor lends me one, watching is not the problem? Is renting one a problem? Is it the possesion on my property?
What if I buy a nice TV to use like a digital picture frame? This way it can hang up and show large sizes of nice, family pictures or other photographs. No TV is being watched, just pictures being displayed?
What qualifies as a TV? Does a computer, which can play streaming TV shows, videos etc count? What about a video mp3 player that can play videos? You can download TV shows to them. Does owning one of those qualify? What if the only thing you download is kosher Jewish music?
What about portable DVD players? Are those considered TV? You can play TV shows, movies etc on them.
What if you need to keep up with the news or stocks for work? Can you not watch the stock ticker? The internet is allowed for work, so why not a television?
The questions on his statement could fill up a whole volume of a sefer! These are just the few that popped into my head at this moment. Is there any sort of speech he made that has the quotation in context?
