How has the DVD player advanced?
the portabe DVD player was invented in 1995
There are a number of possible reasons for a DVD not to play on a DVD player. In an effort to reduce piracy, DVDs and DVD players are designed for a group of large geographical zones, and a DVD intended for the European zone will not play on an American DVD player. Aside from that, the DVD could be damaged, or the DVD player could be damaged. Or not plugged in.
Either the player is wearing out or the DVD is badly scratched and therefore it cannot play anymore. A solution would be to either get a new DVD player if thhe player is the problem, or buy a new disc of the movie if the disc is the problem. You can even purchase a DVD player lens cleaner which is actually a DVD that cleans the gears inside the player.
When considering the purchase of a Toshiba DVD player over a Sony DVD player, one has to consider the type, quality, and cost of each. All DVD players are compatible to every brand of tv's, but many Sony DVD players offer more options when paired with a Sony tv. If you have a Sony tv, I would recommend a Sony DVD player.
