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.

I looked at the article again and still am not sure if you are doing a client/server?Also here is the link to myTV plugin

Why have any drive at all? Why not just boot over you network? No drives, so less heat and less power needed.You could probably get away with a much smaller case as well.
I love the idea of using an IPhone/IPod touch as a super remote. Seems like a great idea for home automation in general.

Since your content is in a NAS and not in the HTPC itself, why use a hdd at all?I simple 4-8GB usb key or CF/SD/... would suffice for the boot drive and draw less power too
access times and transfer speeds shouldn't matter too much because you dont need to boot it up too often

I have enough hardware to get started on this same project. I have 2 different AMD mATX systems, one with a 3600 one with a 5000 CPU. I also just bought a Q6600 when Frys had them for $180, received an Asus G35 board last night. I also purchased a Saphire 3470 on Egg-sale for $40 if needed. I have several WD 640GB drives available. I have spent a lot of time testing with networking equipment and have achieved a 109MBytes/sec throughput to the WD drives. I have all the hardware necessary, but am not sure yet how to configure the system as a whole for the best setup. My current thinking is using an AMD box for the front end, use the Intel Quad horsepower for recoding and processing. I am not sure how much processing the HTPC box can do, yet still play flawless video. I'm sure I want the Intel as a 24/7 server or just a batch processing unit as needed either. Obviously, I don't want to run any more equipment 24/7 than necessary.It would be nice to split your articles into 2 distinct groups. Group 1 would be hardware that works, or doesn't work, like you've mentioned here already, failures are great to see too. List PC and server hardware, and requirements for single and multiroom processing. Group2 would be all the software combinations tried, then accepted or rejected. The earlier post by Havor, trying many different media centers is a great idea.
A diagram of the configurations would be helpful too, both hardware and software to show how it all fits together.
How many CatX and coax cables have you run to handle this? Are you recoding DVDs into AVI? What about ISO or some other format? We haven't even mentioned the satellite/cable control yet. So many things to consider, so little time. I'm itching to fire Scumcast.

Hi Anand its starting to look really great (and i am bit jealous of your theater :-))But have you decided on what Media Center software are you going to use ?
There are 5 main options on the moment
MCE Vista/XP
MediaPortal
Myth-Buntu
SageTV
BeyondTV
You properly have done some research on it, of withs will fit you the best but it would be interesting if you would make a article of all the pro's and con's of the various options they have to deliver.

BeyondTV is really only useful for TV, the media component (BeyondMedia) is lacking in features and is very poorly supported.I've used MCE (both WinXP and Vista) and it's very slick but isn't as configurable as other options. Like Anand, I didn't like the default viewer for MyMovies, maybe I'll look into the one he's using.
I haven't used Sage, MediaPortal or Myth in a long while but from what I hear MP has made a lot of good progress over the last year or so since I played with it.
I'm still running meedio on my HTPC, and even though the developer sold it to yahoo there's a decent community at meedios.com keeping it going. I prefer Meedio's way of handling browsing movies - give me a list of films (I have dvd covers) to choose from, show me some brief info (plot summary, run time, lead actors and rating) and then play it. I don't need all the imdb info, and browsing by letter is a pain. It looks like the video browser anand linked might fit the bill.

I've got my own little ongoing HTPC project- so far I've personally had experience with MCE, BeyondTV and MediaPortal. My personal opinion is that MediaPortal has the best blend of extensibility, functionality, lowest resource footprint, and stability- especially since it is now finally @ RC1. It definitely surpases BTV and MCE in terms of functionality- but that's what happens when you're an opensource project and everyone contributes their own plugins. MediaPortal never had the same issues that BTV had. They've made MP TV-Server installation mandatory with RC1, which mildly complicates the install- but if you're setting up your own HTPC you can deal with it. My current rig is an Athlon X2 3800, sitting on an nVidia 6150 platform, 2 GB of ram, a TV-Wonder 650 (ATSC) and an AIW 2006 PCI-E. Once I find the right 780G board, I'm moving over to that so I can finally start pushing HDMI to my receiver. The only problem is, there's no decent setup yet for EPG in the US without paying for it.I haven't forayed into the Linux world on my little project yet mainly because I haven't properly researched support for my hardware.
I highly recommend MediaPortal for a Windows platform, but I would love to see Anand do a review of the Linux based software. I'm considering Myth-TV, and will probably be testing it in another month on my current rig.

I totally have to agree with you on the MediaPortal option. I just recently discovered it after having Vista's MCE for the past year. The best part about it, you can design and build your own skins for it! I'm currently finishing my MFA, so after schools out, I intend to build a really nice skin for MediaPortal and use that setup for my HTPC.neogodless - Thursday, May 1, 2008 - link
I didn't see mention of what you plan to use for an optical drive, so I assume you won't have one in the final build. Will you rip movies on a separate machine and transfer them over the network? And if someone brings a Blu-ray movie over, will you be able to watch it right away, or will you have to rip it first? How long would that take?
