Question Is rock solid/stable 48mbps adequate for Blu-ray streaming onto and extender?

I have a bedroom I would like to add an HD-200 to that doesnt have an Ethernet port. Also, wireless signal in that room is not 100% stable.

However, luckily the power wiring in our home is pretty decent; which can accommodate Ethernet over Power (Powerline) devices at a steady, minimum of 48mbps. Both "200mbps" and "500mbps" Powerline devices peak out at 53mbps (going from one end of the house to the other); which appears to normal (actually better than average) under real-world circumstances in 2 story homes.

I realize that Bluray format video/audio takes up 40mbps. I just want to know if a stable 48mbps is enough to stream bluray; leaving enough headway for commands and drawing OSD graphics (menu transitions, animations, etc); also, throwing fanart into the mix.

Maybe someone here uses Powerline technology for their extenders for ripped bluray discs?

Below is a rough estimate of the speed I would receive on my HD200 when connected to the Powerline Ethernet cable. With wireless, I can come pretty close to this, but I can't count on it being 100% stable.

From the numbers, I would think you'd be fine given buffering and the speed you have. Reality tells me to advise you just try it out and see what happens and report back.

I think with .m2ts files you would be ok, but if you compress your backups to mkv, you might be on the cusp. 55-60 Mbs would be safer.

I live in a dense urban area, and I found I had too much interference from all my neighbors wi-fi's that I couldn't get my HD200 to work reliably with wireless N. Once I upgraded to 5GHz using a Linksys WET610N Dual-Band N Entertainment Bridge it worked.

That looks like an Internet speed test, you should try something like iperf or jperf to test your LAN speed.

Uggg. for clarification, MKV is only a container. It is not a form of compression. I can take a m2ts file (which is also a container) that has an H264 and audio soundtrack, and put them in an MKV container and you'd need the same amount of bandwidth. This poster is trying to recommend that you recompress the video/audio streams and then put in an MKV container....

Right I was implying that in converting to MKV, many people compress because they don't like the large size of .m2ts files, but this causes burstier traffic requiring more bandwidth. If there is a recommendation with marginal bandwidth I would not compress them. Simple remuxing into MKV would likely be okay but why bother?

Or MoCA, IP over TV coax. Less issues with interference and attenuation on the power lines (HomePlug AV).

Fair enough. I understood what you were saying, but it's a pet peeve of mine when people say something like "compress it to MKV". We both understand what's going on, but I just wanted to make sure the original poster knew what was going on.
