Sure. My point was that there is zero dif between the BD file and a 1:1 copy of it. Sorta the definition of one-to-one.

I discovered that even with a wired gigabit network, some devices just can't handle a full 1:1 uncompressed BR rip. My Samsung plasma smart tv with the Plex client is one such device. It could play DVD rips just fine, but would choke on BR rips. I bought an Nvidia Shield TV to use as my client playback device and that solved all my problems.

thats because of what the device can actually support for audio/video codec support. It's quite possible the plex client on your TV isn't capable of doing a direct stream of the ripped movie thus it needs to do transcoding which causes lots of issues with underpowered devices. The shield has the largest support for video and audio codecs out there. So it stands to reason that there would be less need to do any type of transcoding.

Yes, of course. It is easy to show that a wired gigabit ethernet connection can handle way more than a single uncompressed BD stream.

With newer codecs and 2 pass you can't much smaller files with no perceptible difference in picture quality. BD streams are typically around 23-25 Mbps. You can get really nice encodes using h265 (HEVC) at a fraction of the size. You just need a very fast PC to do this. Same with VP9 except that a player needs to be worked out as those files don't seek very well if you want chapters.

Yeah, yeah. Some of us don't see any need to compress. So no matter how it is explained to us, well ... yeah, yeah.

The files playback fine on my Intel i7 computer with no isses, but my Sony players and Samsung televisions appear to struggle with large files. Once i compress the file down to under eight 8GB, the issues go away.
You need a real media player. I have no issues playing back 1:1 50GB BD ISO rips or 35+GB MKV 1:1 rips with my PCH media players. Playback starts right away or within a few seconds at most.

Compressed videos actually eat up more CPU than uncompressed bluray, assuming one is using x264's more powerful switches. Uncompressed bluray is easily played on most devices due to dxva compliance.

Where do you get uncompressed blu-rays? All of mine are H.264 or VC-1.

With codecs you can get a wide range of compression options. BD's are generally near lossy encoding settings. Some screen capture apps will use high bitrates so frames aren't easily dropped and minimal encoding is done. Of course with BD's video is only part of it some of near lossy audio codecs eat up a bit.

BD chipsets have evolved over the years. I'm one of the AVS folks who had the AVel Linkplayer2 which turned out to be a beta test of Sigma Design's BD chipset. The product manager actually hung out on the topic here. Anyway, as hardware people will tell you chipsets get optomized so they can efficiently decompress highly compressed video files.

Not worth the time and effort imo to compress the video. Audio compressed to 640k AC3 5.1 is fine for me.

I kind of assumed that people on this thread would know that I was talking about recompression when reading my post in context to the post I had quoted.

The important part is that it's a lot easier, hardware wise, to play a non-transcoded video vs one that is. This is of course assuming that you are breaking dxva compliance and having the CPU do all the decoding.

It's funny, but I fall in the opposite camp. I have a harder time seeing the difference between a transcoded video stream vs audio.

As you age that will become more and more the case. You might even be looking forward (hah!) to redoing your videos at increasingly lower and lower bitrates!

Yes, I was being sarcastic. That's why I put the winky face at the end.

I never worried too much about being compliant to any standards. I just know if I use the high profile and level 4.1 limits in Handbrake I can direct play the video on all of my hard wired players in the home. Maybe they are compliant, maybe not, I just know those settings work for me. I will note my Rokus are pretty finicky about audio. They won't direct play AC3 so anything I record needs the audio transcoded or re-encoded. At least they can play AAC.

Well, of course that is one way to look at it.
On the other hand, as we have aged I've managed to make my wife understand that we need progressively larger displays -- we're up to 65" in the family room and 50" in the bedroom. Next stop will be an 80" OLED, some day. In the mean time, a revamp of the family room audio system is on the horizon -- time for bigger speakers to compensate for all that hearing loss.
