Is there really any reason to have inet on the 3D BR player for just this function?
The main reason for having an internet connection for your blue ray player is to be able to painlessly
get the firmware updates. These updates are more important than ever. You can't compare the blu-ray disks to the older regular DVD's. Blu Ray uses java script and thanks to the designers of java who like to make work for themselves, love to rewrite the code and update the authoring which requires the players to be in constant need
of updates. If you don't use the internet you may be jumping through hoops to get those updates, by going to the manufacturer's website for maintenance support with your computer, downloading the update burning it to a CD and then putting the cd in the player to do the update. You will find out if you need the update when you try to play a new title and the menus lock up your player, or just won't play the disk at all. Trust me, you'll curse the day you fought connecting the internet cable to your player.
In my Home theater, I saw this coming about 8 years ago so I ran a Cat 5 cable from my router to the back of the equipment cabinet, then added a 5 port switch. While wifi is certainly easier today, not all equipment has wifi capability so having a wired switch to connect to has made the process easy. I now have 8 port switch back there and it is fully tapped out.
You don't have to use the added features like wigits for Blockbuster online, netflix, weather and childish games these players also have but the one thing you do want is internet player updates.
Then if you don't want to mess with the updates, you could always just stick to regular DVD's And in case you haven't figured out yet, 3D has nothing to do with this. It's BluRay that began the need for updating the firmware.
