A:AnswerI purchased the 420 for the fact that it has all the qualities of the 820, except Dolby Vision. DV was not a 'must have' for me, so the price difference was a major factor.
A:AnswerI did not see any useful apps besides Netflix. The interface looks like something out of 1997. Probably best to supplement this with something like a Roku or Apple TV.
A:AnswerThis is a 4K/3D/Blu-ray/DVD player. It will play 99% of DVDs. If you have an old DVD/vhs or just DVD player and have a lot of older movies, I recommend keeping the old player. There have been so many transfer techniques used to create DVD’s that sometimes a DVD will play on an old player but not a new one. You might be amazed at how beautiful some well-created DVDs will look on this player- the picture quality is outstanding.
A:AnswerYes, it does. I have personally played DVDs, Blu-Ray, and
UHD Blu-Ray discs in this player. If you check the owner’s manual for this player, it shows it can play the following types of media; UHD Blu-Ray, Blu-Ray, DVD, CD, and USB.
A:AnswerYes, this 4K player will work with your 4K TV by connecting with an HDMI cable. Not sure what your Cablevision has to do with the Panasonic 4K player unless they also provide your internet. If they do, the player can connect to the internet via Wi-Fi or hard wired via ethernet to your modem and stream 4K content.
