Is the BD player a 10Mbps device, perhaps?  If your CAT-5 wiring in the 
wall is flaky a slow device will still usually work, but the 100Mbps 
Transporter would have a problem.

The most common wiring error is to run all the pairs in sequence across 
the ethernet jack pins, instead of swapping the specified wires between 
pairs.  Here's the wiring spec:

At one of my computer clients I replaced a 10Mbs switch with a 100Mbps 
switch, and one of the PCs then wouldn't connect.  It worked fine with a 
long patch cable so I suspected the wiring, and when I checked I found 
that run had been wired incorrectly.

Even if the BD player is 100Mbps and works OK, I would still check the 
wiring, as each device may respond differently to incorrect wiring 
conditions.
