Dvd Not Recognized By Sony Blu Ray Player in Toast 14 Posted August 7, 2016 · Report reply Anyone have thoughts? Is this a software issue? A Sony issue? A disc issue? "Yes." To start with, you've pretty well proven that your discs were created properly since they play in a couple different places, including a set-top DVD player. (Possibly one of the inexpensive, $40 (or less) DVD players? ) Next point, Memorex discs are considered by many, including myself, not worth the money you pay for them. Again, you've proven the disc(s) are written correctly, and readable in more than one device. Point three. More expensive players have been known to be more particular about what type of discs they will read then computer and inexpensive players. I had a $25 Magnavox DVD player that would play pretty much any disc I put in it, where my $300 Sony DVD/VHS combo wouldn't ready half of them. My suggestion is to try some different brands of discs. Historically, Verbatim discs have done well by most people. It's a cheap thing to try.
