Software Interface: XBMC and JRiver Media Center 18
The combination of MPC-HC and LAV Filters enabled us to play back all our media files without issues. However, the user interface is not really amenable to a media center experience. XBMC, undoubtedly, has set the gold standard for the HTPC user interface. It is possible to go through hoops to make XBMC use MPC-HC and LAV filters for media playback, but the XBMC UI is lost during playback.
XBMC's internal playback engine incorporates DXVA capability also. It works very well for most common media files (standard TV broadcast recordings and Blu-ray/DVD re-encodes in MPEG-2 / MPEG-4 / H.264). However, interlaced VC-1 clips pose a challenge even with DXVA disabled.
Interlaced VC-1 Playback in XBMC (non-DXVA Mode)
If you don't particularly care for madVR or don't have any interlaced VC-1 clips in your library (and don't plan to add any), XBMC is a very good choice for the software interface to a Intel-based HTPC like the one we are discussing right now.
If you have already tried XBMC, but still have unmet requirements in terms of technical capabilities, I would definitely recommend taking a look at JRiver MC18. The UI (Theater View) is a couple of notches below XBMC, but it more than makes up for the lack of eye candy and ease of navigation by completely handling the configuration of madVR and various codecs without user intervention. We have covered the Red October initiative before. On our testbed, we were able to get perfect playback of all our clips using the Red October standard profile (which doesn't use madVR).
Interlaced VC-1 Playback in JRiver MC18 (RO Standard)
From our experiments, the combination of LAV Video Decoder (QuickSync) + madVR with default settings should work without issues. A similar profile is used in Red October High Quality (RO HQ) (some of JRiver's own filters are added to the chain), but we had plenty of dropped frames during playback of 720p60 / 1080p60 / 1080i60 streams. I am in touch with JRiver to investigate this issue further and will make it a point to update this section in case the status of RO HQ on the HD 4000 changes.

I've run many tests doing the 8 VS 7 comparisons. Not only have you left out many of the comparing scores for 7, but your power usage numbers don't seem right.I have a Kill-A-Watt power usage adapter that plugs right into the wall, which measures total power running through it. Last night I ran tests using Netflix and 8 vs 7 on two different notebooks. The first is a Gateway P-7811FX[P9700 2.8 ghz C2D, GF 9800m GTS] and the second a Toshiba L655-S5150[i5-480m 2.66ghz, Intel HD]. The numbers for the Gateway were 67.3[8], 64.4[8 app] and 66.1[7]. The Toshiba's numbers were a bit better, 50.9[8], 47.1[8 app] and 50.8[7].
Now I could go one for days about game benchmarks and compatibility between 7 & 8. But real issue here is the your power numbers don't seem realistic. The Netflix app does have a small advantage, but nothing as dramatic as what you are showing. The difference between 8 VS 7 numbers are statistically insignificant. I ran battery tests as well. And those numbers are also statistically insignificant.
I'm not willing to accept your results as valid and quantifiable, unless you declare the testing equipment used and OS config setup.

And before anyone states the obvious, yes the CPU's in each of those notebook were upgraded from their factory offerings. Both have 4GB of ram. The gateway has a WD 500gb 7200rpm HDD and the Toshiba has a Seagate 320GB 7200rpm. But remember these notebooks were not compared to each other, only themselves using one OS vs the other.ganeshts - Monday, January 21, 2013 - link
I stand by my numbers, and the tests were repeated multiple times to confirm this. Our configuration of the testbed itself is described in the first page of the review.For power measurement, we use the UFO Power Center from Visible Energy with a custom power measurement script described here:

I see that both the CPUs you used have old Intel HD Graphics (yes, Clarkdale and Arrandale were released when Intel HD Graphics wasn't that great). I think a lot of the advantage for the app version has to do with very good hardware decode acceleration (improved GPU and drivers).

You're claiming that minimal power savings with old architecture CPUs on notebooks (were the batteries plugged in?) as measured by you invalidates Ganesh's measurements on a desktop platform? Just... no.Galatian - Monday, January 21, 2013 - link
Does the Windows 8 GUI actually bring something on the table for a couch potato like myself? I just retired my old gaming rig which now serves as a HTPC and I kinda tasted blood with Steam in Big Picture mode. I'm planning on running a power efficient yet graphically powerful HTPC once Haswell (or perhaps a new AMD A10) is out, but I would really like for Windows 8 to be completely controllable by an XBox controller? Has Microsoft actually included support for that or was their only new feature touch support?lexluthermiester - Monday, January 21, 2013 - link
You can control Windows 7 with a 360 controller? Didn't know that. Is this something natively supported? Or is it a hack? Wait... I'm on the net I'll look it up... Very cool if it works though.Galatian - Monday, January 21, 2013 - link
Never said it did...not sure were you red this in my post??? I was just curious because for me the tile based start menu of Windows 8 would seem to be a perfect fit for a XBox controller support, hence my question. At least this would be one place in my house were Windows 8 might be useful. If not I'll jus stick to Windows 7Gigaplex - Monday, January 21, 2013 - link
If your TV is 720p rather than 1080p, then absolutely not. "Metro" apps don't run at 1280x720, an error message pops up telling you to change the screen resolution whenever you try to launch one.And no, sadly an Xbox controller doesn't work with "Metro".

LOL seriously?I mean I know that the minimum is 1024x768, but hell, everyone knows 720p is often used and thus I thought they were smart enough to allow that resolution, even if its not quite as high in the vertical. The stupidity of MS never ceases to amaze me...

Unfortunately the Metro/Modern UI is neither remote friendly, nor controller friendly.Waste of time for a HTPC tbh.
