i had the most problem with was the proprietary coding to add a wireless adapter to the unit.

This player constantly looses its code for connecting to Netflix and I have to go online and enter a new code to activate the player for my account.

Blame Samsung engineers, blame your internet provider, blame your local telephone service or cable provider, blame your DSL box, blame Netflix for not supplying sufficient bandwidth, blame sunspots (which interfere with wireless transmissions), blame your router, blame your neighbor's WiFi for interfering with yours, blame your neighbors for all checking their email at 6PM, blame your neighbors for hacking into your WiFi because you were too lazy to chose a hard-to-hack WEP code, blame your son for using up all your bandwidth playing online videogames, blame global warming (no reason), blame your ethernet connection, blame your ethernet cables, blame your HIMI cables (which may be too long or an old version), blame those horrible flourescent light bulbs the Government is forcing us to buy (which cause radio-wave interference)----but don't blame the BD-D5000.

It plays regular DVD's, Blu-Ray's and 3-D movies very well

But as for the Samsung products, when they work, its beautiful, so nice to use the tv remote to control the blu-ray player, and all the optimal picture settings and 3-D settings work automatically because of the Samsung connection

The 3-D is great
