Despite claims to the contrary, Intel doesn't seem to have delivered perfect 23.976 Hz refresh with the 23 Hz setting yet. We tested out with the driver release on Sep 1st, 2012 (v9.17.10.2849). In fact, with the Vision HT 321B, the accuracy is slightly reduced compared to our Ivy Bridge HTPC testbed.
Other refresh rates follow a pattern similar to what we saw in the original Ivy Bridge HTPC review. Refresh rates such as 24 Hz, 30 Hz and 50 Hz show improved accuracy, but 29 and 59 Hz settings are not as accurate as we would like them to be.
One of the improvements we saw in the Vision HT 321B with the latest drivers was the fact that the 50 Hz capability of our Sony KDL46EX720 was correctly recognized. However, our complaints pertaining to ease of use of the custom resolution settings still remain.

Could you test the silent data corruption issue I have described in Vision 3D comments? With Vision 3D it is still an issue when 16GB RAM are installed (with 8GB RAM they fixed it via BIOS update that they did not make publicly available) and ASRock although acknowledges its existence refuses to fix it.ganeshts - Monday, November 12, 2012 - link
I will follow up on this with ASRock. That said, I have been using the Vision HT / Vision 3D 252B to unpack a number of split archives (around 400 MB each unpacking to ~4.37 GB / ~10 GB) and not found any issues so far.But, definitely an interesting case (if there is some data corruption with a different DRAM, that may point to some issue in the DRAM module itself). Are you aware of any other users with the same issue? I am trying to see if there is something common between all the systems exhibiting this problem...

It will not complain at unpack because my thinking is that corruption occur at writing (at some point in my lengthy mail exchange with ASRock support Intel ME was mentioned as the culprit). I discovered the issue because par repair invariably fails on large file sets. That is why I call it silent. Did you try to create checksum of archive content and test after unpack? I have only one set of laptop 16GB modules. But when my 2nd gen Vision 3D had BIOS prior to 1.10c ("c" suffix is important here) it was present with 16GB and two different sets of 8GB modules.klmccaughey - Monday, November 12, 2012 - link
I don't understand why manufacturers can't release a cheap HTPC. It is still much more cost effective to build your own.Every time I see one of these reviews I get excited, and every time I get disappointed as I see the outrageous price tag.

I too wish there were cheaper alternatives. I myself have no need for optical (Ew), and am usually eyeing those tiny foxconn's that use E-350's. Though I'd more likely go with something with more performance.Perhaps this segment is too much of a niche (Probably). Intel's NUC looks promising, hope it becomes standardized so that the race to the bottom can start on those chips =P.

Avoid the 350. Yes it will work, but a lot of use end up being slow on it especially when the GPU acceleration isn't available.StealthX32 - Monday, November 12, 2012 - link
From what I've read on a few Newegg reviews, you can get a Broadcom BCM9700xx hardware decoder card to put into the miniPCI-e slot and achieve <20% CPU utilization on even high bitrate 1080p material.I bought this from them when they had the buy an HTPC get a free SSD combo, but haven't gotten around to buying the Broadcom card yet.

As I said, it's doing everything outside of the GPU accelerated videos that ends up being very slow. Web browsing, Netflix, etc is all CPU limited.BuddyRich - Monday, November 12, 2012 - link
Netflix via website and silverlight is bad.Youtube HD is GPU accelerated and Netflix Win8 also works nicely.
One of the few pluses of Win8!

I have an E-350 based Zotac Nano.It's absolutely silent, can play most media content without a hitch (haven't tried 1080p60 content though, but 24 and 30Hz are not a problem) and with Windows 8 internet browsing and general PC usage is butter smooth.
Sure, i wouldn't do media transcoding or rendering or content creation on such a PC, but for the value and intended use I couldn't be happier.
