Agree...bitrate is the key measurement. I get my bandwidth measurements using LAN Speed Test (www.totusoft.com
), which measures a standard TCP file transfer.
I'm streaming to an LG BD570 and an LG BD670. PC-->WNDR3700-->MoCA-->player. Wireshark indicates the CIFS streaming takes place using TCP (rather than UDP). Wireshark doesn't indicate any dropped packets or other TCP errors when streaming stuttering video to the players. The "solid 84Mbps" measured with LAN Speed Test is PC-->WNDR3700-->MoCA-->GigE Switch-->laptop.
A 16Mbps 1080p mkv will play correctly from a USB drive connected directly to the player. Additionally, the same file will play correctly from a NAS connected via Cat6 to the player through a GigE switch (NAS-->GigE switch-->player). Since the video(s) will play correctly via USB, I think
that means I can eliminate CODEC incompatibility or video file errors. Since the video(s) play correctly from the NAS via ethernet, I think
that means I can eliminate the NIC in the player. My next troubleshooting step is to connect directly from the router to the player. After that, I'll connect directly from the computer to player. Between those two troubleshooting steps, I should be able to determine if it's the MoCA, the router, or the computer causing the stuttering (despite the "solid 84Mbps" measured with LAN Speed Test). I wonder if there's simply more TCP overhead going through the router and the MoCA that is eating up a healthy chunk of that 84Mbps bandwidth.
Sorry...I didn't mean to turn this into a personal troubleshooting thread. Rather, part of my purpose for writing was to note how important it is for us to state overall bitrate (and surge bitrate) when making capability comparisons and HD streaming claims.
