Network Streaming Performance - YouTube
YouTube is one of the most popular video streaming services, and Google maintains a number of encodes for each stream. On platforms supporting Adobe Flash, FLV streams are available at resolutions ranging from 240p to 480p. HTML5 streams are either in WebM (for Firefox) or MP4 / H.264 (for Internet Explorer). WebM streams typically top out at 720p, while MP4 is the preferred format for 1080p. At higher resolutions, Adobe Flash also streams the MP4 version.
As expected, we get GPU acceleration when using Adobe Flash in Firefox on Windows 7. The debug OSD presents the requisite details.

Windows 8 has an app for YouTube, 'YouTube Player' which allows for stream quality selection. Just like the Netflix app, there is no direct way to determine if GPU acceleration is being used.

We will rely on the power consumption at the wall to determine the efficiency of various ways to stream YouTube videos across different operating systems. Since the matrix of options is quite big, we present the graphs one at a time. All the graphs are on the same scale. Press the button below corresponding to the combination you want to compare the current graph against.
It can be seen that the Windows 8 YouTube Player App wins hands down. The stream being decoded is, in all probability, the 1080p H.264 version. Even when Adobe Flash is being used, Windows 8 seems to be more efficient compared to Windows 7. If you are on Windows, and prefer to use HTML5, it is better to avoid Mozilla Firefox because the WebM version consumes the most power at the wall (due to lack of hardware accelerated decode) while providing only a 720p stream. Once again, if YouTube forms a major part of your HTPC experience, an upgrade from Windows 7 to Windows 8 can be recommended.

In every test I still wonder about how Linux/Ubuntu (insert random distro) will preform these task...how would a linux setup do it's job? :)Gigaplex - Sunday, January 20, 2013 - link
It's usually pretty good with the proprietary NVIDIA drivers. Other platforms, not so much, you're generally better off with Windows in terms of performance.powerarmour - Monday, January 21, 2013 - link
Pretty good with the Intel Mesa drivers too, VA-API is quite well supported now, especially in XBMC.Fx1 - Sunday, January 20, 2013 - link
Home Theatre PC? LOLMy Panasonic GT50 will play MKV ripped full 45gb Blu rays right off a HDD without problem
i have netflix and a ton of other video stuff right on the TV.
I fail to see why you would spend any money on a HTPC any more.

Your Plasma TV has built in CableCard tuners and terabytes of storage for DVR duty? CableCard leases are usually ~$2 a month vs. ~$10-20 a month for DVRs from your cable company. It's easy to have 8+ HD tuners with basically limitless storage with WMC. HTPCs can be a lot more than glorified media streamers, and your TV doesn't come anywhere close to fulfilling all of the use cases a HTPC can.Fx1 - Sunday, January 20, 2013 - link
For a start the UK doesnt suffer your cable company issues. We have 2 providers that are not that expensive and include DVR for FREE. Plus you can connect a 2TB HDD to the TV and play Blu ray rips and record like a DVR on the same drive. God knows why you would want to store all those TV shows anyway they are pretty much on every torrent website anyway. Quite frankly a HTPC in this era just isnt worth the money. No matter how you spin itganeshts - Sunday, January 20, 2013 - link
Problems start cropping up when the decoder in your GT50 refuses to play the MKV off the torrent site.I bet your GT50 doesn't do HD audio bitstreaming, and I am pretty sure the online experience (quick check up of something on the browser or automatic metadata downloading) doesn't work out to be the same as that of a HTPC.
Even without using tuners, I would recommend going the HTPC route if you can afford it.

I just recently ran into the problem where my Samsung TV would play some, but not all MKVs I've downloaded. Plus, the interface for playing video files on a NAS is terrible on all devices. Pretty much any app is better. UI, metadata, and remembering how much of a video you played is just as important as being able to watch a video.Bob Todd - Sunday, January 20, 2013 - link
DVRs usually aren't really "free", they just increase the package price to compensate. My HTPC has already paid for itself and is now saving me money every single month. That isn't "spin", it's just a fact. And your entire post is ludicrous considering you are pointing out geographical differences and that your situation doesn't match everyone else's, then turn around and say nobody has a reason to have a HTPC. Your provider gives as many DVRs as you want for free? Here some providers include one "for free" but the package is really another ~$20 a month vs. leasing a CableCard. And every 2nd/3rd/4th DVR or STB you need is more money out the window every single month. It cracks me up how myopic people like you can be and how you think your single use case applies to everyone on the planet.Fx1 - Sunday, January 20, 2013 - link
Our 1TB DVR is free and quite honestly not that much of a big deal. There must be some weird American obsession with recording tv shows that the rest of the world doesn't share. To build a pc for the sole purpose is pretty extreme.Also I have yet to have an mkv that won't play on the Panasonic tv. I was surprised myself but really this review just shows how a htpc is just an excuse to build a pc
