Yes. If the Panasonic system has a HDMI input, you can use this. Some 'home cinema systems' are merely DVD players with built-in amplifiers. These types of systems do not have HDMI inputs, so cannot be used with other players.
Beacaus bluray is newer and they think everybody has a bluray player... eventually it will come on dvd.
The Panasonic SC-BT series (there is no SP-series) are theatre-in-a-box systems with a disc player with built-in amplifier. You don't need a receiver for this. Your Samsung would also have its own amplifier if it has speaker outputs. These two systems wouldn't connect to each other, but you may be able to use the Panasonic's speakers with the Samsung.
A DVD player is a better decision than a BluRay player based on price alone. This type of player is cheaper. A BluRay player may be a better idea because it can also play DVDs and has more advanced features.
No. You need a BluRay player that specifically says it can read 3-D disks
Panasonic offers a lot of car media players that you can purchase and have installed at Best Buy. They are really good for long road trips and are of the highest quality.
A DVD player cannot play a BluRay disc. A BluRay player can play both BluRay discs and DVDs.
If you already have a Netflix account, you just need to enter your account information on the BluRay player's Netflix menu. If you don't have an account already, you will need to set one up on your computer so that you can get the account information that the BluRay player needs.
Panasonic DVD players can be purchased from all common electronic stores. For example, if one wanted to visit a brick and mortar store, they could try Currys. Online they can be purchased from Amazon.
No
No. DVD quality will be displayed whether the player is a DVD player or a Bluray player. DVDs won't be the same quality as a Bluray disc of course.
