The Second Try: NVIDIA GeForce 8200
Shortly after building the system I received an ASUS M3N78-EMH HDMI based on NVIDIA's GeForce 8200 chipset; seeing as how the NVIDIA GeForce 8200 chipset supports 8-channel LPCM audio over HDMI, it seemed like a better solution for my needs so I gave it a try.
| Idle Power | H.264 Decode Power | |
| AMD 780G | 53W | 66W |
| NVIDIA GeForce 8200 | 38W | 68W |
Power consumption under load remained unchanged however at idle the GeForce 8200 system pulled significantly less power. This didn't jive with Gary's power consumption numbers, but apparently there may be some issues with the ASUS motherboard inconsistently supplying CPU voltage resulting in power consumption that ranges from significantly lower to on par with the AMD 780G chipset.
Other signs that the GeForce 8200 isn't ready for prime time included basic stability. During its tenure as my HTPC motherboard the Gigabyte 780G never crashed on me while watching a movie, however a few minutes into me playing around with Jet Li's Fearless and the system bluescreened on me. I haven't been able to get it to crash since, but stability is of the utmost importance.
The ASUS GeForce 8200 also spins fans attached to it at faster speeds than the Gigabyte 780G, not because it needs to, it just does. We've already made ASUS aware of the problem, which apparently happens on at least one other 8200 board according to Gary.
Installing the Scythe Andy Samurai Master on the ASUS board proved troublesome, the Socket-AM2 heatsink clip interferes with the heatsink on the chipset.
There's also a good deal of noise coming from the voltage regulators whenever there are certain types of disk accesses. The motherboard emits a high pitched sound in sync with the disk accesses that seems to be worse when using the Supertalent SSD vs. the WD 1TB drive. It's by far the loudest thing about the system when in a case.
The final complaint I have about the GeForce 8200 is the least scientific; for whatever reason the system feels slower at navigating through Media Center than on the 780G. I have to switch back to the AMD 780G to be sure, but it definitely feels like it.

Or rather than ripping at full bitrate, you could reencode to something smaller, so you can get 5-10GB per movie and still have a good quality 1080P output. AutoMKV is the new tool for stuff like that.legoman666 - Thursday, May 1, 2008 - link
I rip all of my movies to h264 + ac3 in a mkv container. Just because you illegally download movies in mkv format does not mean that everyone else does also.kevon27 - Thursday, May 1, 2008 - link
I only do bluray... DVD's are for the peasants. I not going to subject myself to that low quality bit torrent stuff you commoners are use to.Pip-pip!

You know, you can rip bluray, bluray rips are also available online.... In fact I think anand specificall discussed ripping "high deffinition content" in mkv format... what do you think he means?Locutus465 - Thursday, May 1, 2008 - link
Ok, so how does that iPhone web interface work? I was thinking of developing somethign for PPC that would allow roughly the same kind of access, but I guess if there's stuff in the works I'll just check that out.crimson117 - Thursday, May 1, 2008 - link
It's just a web interface that happens to work in the iPhone browser. You could also access it from a laptop or desktop on your network.I'd love to see a developer come up with a native iPhone app for controlling media setups, though I expect there'd need to be some special software running on your media pc.

Exactly, the options are two-fold:1) Develop an iPhone optimized website (ala digg.com/iphone or iphone.facebook.com), or
2) Create an iPhone application that triggers web services running on the HTPC itself.
With the SDK due out this summer, I'm hoping the latter will be a possibility.

Perhaps I'll see what can be done on PPC and put it out there then so non-GSM/apple folks can enjoy that kind of fun ;)cghebert - Thursday, May 1, 2008 - link
Anand,sweet setup! Will you guys be doing any of your HTPC stuff with windows xp for those of us who haven't yet "upgraded" to Vista?

Check out myTV plugin for media center for managing your tv shows. It works much better the video brower or mymovies because it uses a full database and downloads all the episode and show information from the web. I use it to manage all my recorded and downloaded shows.Also are you going to install a ATSC tuner? This is one of the best things about media center. I have dish too but the offair recoreded shows look much better on media center than on dish.
If I were you I would move the storage for the dvds and media to a fileserver dedicated for this purpose. You can then not have to worry so much about noise because you can hide it away from the rest of the rack. I run a gigabit network and have no problem playing recored HD shows or ripped dvds on 3 differant computers at a time. The only storage I have in my media center pcs is for recording show off the offair antenna. This is only because some nights I am recording up to 3 hd shows at a time and I am afraid that that and the playback may be a little to much for the network to handle.
Also myMovies and myTV both work great in a client/server setup you can put the database servers on the media server and then any changes you make on one computer will be reflected on all.
I have also tested a htpc with the same chipset that you are using and to me it seems to be really slow compared to my other intel/nvidia based htpc. It even has some trouble decoding recoreded hd shows fast enough to not to get skips and audio sync issues. I would stay away from it.
