To test with LAN Speed Test you need at least a Windows PC and a network share. To test more robustly, you can ran LAN Speed Test server on one machine and the client on another.
Will it be straight out streaming of the blu-ray or will the host machine be trying to do some transcoding? Are you streaming to your PC or a TV? My experiences with blu-ray seem to indicate the client trying to process the file has more problems than any type of throughput.
For examples on throughput you could see, check here: http://www.homenetworkenabled.com/fo...uld-you-expect
