Powerful connectivity options: The BDP-
95 is equipped with a hard-wired RJ-45-type
Ethernet port, a wireless-n Wi-Fi adapter, an
eSATA port, and two USB 2.0 ports. As shipped,
the player can play music, video, or photo files
from USB or eSATA drives, and can also stream
certain types of content from the Internet. It
cannot, however, function as a USB DAC,
although it unofficially provides DNLA Server-like
“Experimental Functions” that potentially allow
the BDP-95 to play digital audio files stored on
PCs attached to your home network.
