I just received the BD-C5500 for Father's Day (purchased from Costco), so I have had it for three days (not counting today b/c I am away at work). I wanted this unit because it provided Netflix streaming/DVD/Blu Ray/DNLA (pretty much in that order) functionality in a single component for our rather small bedroom. At the moment I am undecided as to whether or not I am going to keep it.
I have not yet had the opportunity to watch any disc based media; however, in the 3 days that I have had it, I have had to reactivate Netflix 4 out of 5 attempts to watch streaming content (wired connection). This is quite a PIA considering that my PC is located on a different floor. Last night, the wife and I wanted to watch a show once we were finally able to put our feet up and sure enough we were greeted with the "Do you have a Netflix account?" screen when we tried to stream a Netflix show. I was not about to get up and reactivate the machine so we ended up browsing some YouTube videos. Not quite what we were looking for; however, it was nice to have a "Plan B" available.
So far, activation difficulties aside, I have been pleased with the Netflix quality (watching on a Samsung LN32B540). I have watched a couple of HD shows which seem to be fine; however, I did notice some interlacing issues with an SD show my kids were watching (periodically throughout the show for brief moments I could see the separate lines from each field). On another Netflix related note - it is disappointing that the Netflix interface only has the "Instant Queue" - there are no tabs for various genres and no search feature.
I definitely do not like the illuminated touch-sensitive function buttons on the front of the machine. There are a total of four (open/close; stop; play/pause; and power) which are illuminated with white LEDs (I assume they are LEDs). The lights are OK during normal viewing; however, the illuminated power button is actually quite bright when all other lights are off (note - only the power button remains illuminated when the unit is off). So far I have not been able to identify a way to "turn off" the power button without unplugging the unit- my wife has taken to covering the unit with a towel at night. I am contemplating sticking electrical tape over the power button; however, considering that the button is touch sensitive, I wonder what effect this could have.
I have noticed several other posters have mentioned the Netflix activation bug. This is really my biggest gripe. I can deal with the other quirks, but frequently having to reactivate the machine to stream Netflix will likely be a deal killer. I wonder if this is a bug that can be corrected with a firmware update (note - I am on the latest firmware as of 06/21/2010)? If so, will Samsung even bother to address this (assuming that this is a Samsung bug)? Given Costco's return policy, I plan on giving this unit some more time as I do like the feature set, but if the frequency of Netflix reactivations holds pace I will return it for something else.
