I just bought a BD-P3600 on Saturday, and spent a bit of time tinkering with it.
Here is my configuration:
Samsung 40A530 for my display.
Yamaha RX-V463 amp set up with 5.0(no subwoofer)
I am using a fiber-optic cable for my audio direct to the amp, and for now, component video cables to the display. The amp only supports HDMI 1.2, so I figure that the audio going direct via toslink and the video going direct from the player to the display would make the most sense.
For the networking, I have been having problems with the DHCP from my router, so going with manual TCP/IP settings are what I had to do. This has nothing to do with the player since one of my computers has the same problem. So, I blame the router for DHCP issues, so others may or may not run into problems. I am getting three bars out of five for the wireless signal strength. For people who can not get their player to talk on the network, you may want to try setting the IP address, subnet mask, gateway address, and DNS server manually.
I will note here that I observe the need to shut down the unit after several hours if I want to change from Pandora to a disc, and that using the browser to stream content from computers also stops working after some time. Rebooting the unit resolves this, and I suspect the wireless networking is a little buggy. This should not be a show stopper for most people, but it is a little annoying. So, if it is working and stops responding, a quick power off and on again may resolve this.
Since Microsoft networking is a little funky, some people may run into issues sharing their files on the network. Again, this can often be caused by computers(some just don't like to share, some machines won't show up without some tinkering when you browse from other computers, etc). What this means is that the player not seeing one or more computers may be the fault of those computers that are not being seen and not the player.
For disc playback, I do not have another BluRay player to compare with, but the BD-P3600 has a requirement that you use HDMI to upscale normal DVD discs. Also, output is limited to 1080i with component video cables which are not even included, just the old "yellow" composite and red/white cables. Why they would include the old red/white/yellow cable but not a component video cable is beyond me, but I will mention it when I call Samsung support on the other issues. I did have to reboot the unit before playing a BluRay disc because I had been using the Pandora service, and it wouldn't let me play the disc without a reboot. As I mentioned, it seems to be a networking code issue that requires a reboot to clear up.
The network/wireless issues are slightly annoying, and getting a message that I could not play a new BluRay disc after using the Pandora stuff for several hours concerned me until I rebooted and it worked right away. Those not streaming from their computer or using Pandora/Netflix may never run into these problems.
Needing an HDMI cable to get access to some features is slightly annoying, and I do not know if other players have this problem, or if it is just this unit that has it. I plan to buy a HDMI cable today so I can check out the DVD upscale capability.
