Building a HTPC if you have a high defintion TV or projector is really worth it.

(this all only applies to component output, not s-video or composite, to a HD-Ready TV or front projector)

It was hell to setup properly but it takes my progressive scan DVD player (which I thought was good...real good) and beats it to a bloody pulp.

It's not even a dedicated HTPC, its just my main computer with some 30 foot home made component cables going to my TV.

AthlonXP 2400+
1.25GB
ATI Radeon All-in-wonder 9800 Pro (this is the key piece....component output built in)
SB Audigy 1 OEM (used to pass Dolby 5.1 and DTS signals to my receiver)

If you were building a dedicated HTPC (home theater PC), you wouldn't need an expensive AIW card...just a simple Radeon 9xxx of any kind would work because there is component output dongles (plugs into the DVI port) available from ATI.

And my HT electornics are:

Toshiba 50h82 HDTV (50" 16:9)
Yamaha RX-V496

Positives of a HTPC

-Output to your HDTV/projector at its native resolution. A lot of TVs convert incoming signals to their native and quality is lost. The only type of signal that my TV leaves untouched is a 1080i signal (usually 1920x1080). I send a 1776x1000 signal to it (with 1080i timings so the TV thinks it is true 1080i) to prevent extra overscan.

-Software decoding is immensely superior to hardware decoding in every which way unless you spend upwards of $15,000 on video processors, scalers, line doublers, etc.

-Potential for extra image processing and enhancing. Mainly a little program called ffdshow. It's meant for DIVX/XVID but you can set it to affect your DVD video in certain players such as Zoom Player and TheaterTek. You would be surprised what ffdshow can do to a measily 480p dvd image. It lets you do high quality resizing (to whatever you are outputting at) to bypass your video cards scaling which is inferior (again...hardware). There is also other filters you can use such as dscaler sharpen which brings out the finer details in the image WITHOUT adding edge enhancement or extra artifacts. This takes enormous CPU power. It'll quickly bring 3Ghz P4's to their knees.

Here is an example of how close you can get to the HD broadcast with the original DVD image.

-Truer to the original source. I was amazed at how flawless I could get AVIA settings. Color, contrast, everything is better. Every DVD player handles it differently and has different flaws but software decoding is much better.

-If you're a fan of the theater atmosphere, there is software available to play predetermined (or random) trailers, dolby and thx demos, etc. as well as trivia slides before the feature starts.

Negatives

-"Stuttering" on slow, long pans. This can be fixed (in most cases) with an app called Reclock. Works like a charm for me.

-The potential for quality is so great that sadly the majority of DVDs just don't look good anymore because it brings out all their flaws. I was flabbergasted how bad Aliens looked (from the Quadrilogy set), however the original Alien looks fan-fvcking-tastic. The other two are above average and look great.

-Not as convienent as the set top player. Took me over a week to get everything as I wanted it. But I have an ATI Remote Wonder which gives me almost all of the functionality of a normal remote. Chances are no one else in your house will be able to operate it (that can be a good thing sometimes ;) )

-You become even more anal about quality. You distaste for so-and-so's latest DVD transfer will start creeping up in every day conversation :Q


Anyway this is the cliffnotes of it. If anyone has any questions I'd be happy to answer them. Definitely worth the effort if you think it can never look good enough.

Here are some comparisons of before and after processing:

For me, it's not worth the emotional toil you've mentioned. With my progressive scan DVD and component output I'm doing just fine.

Straight DVi-to-DVI on TVs that have the input is more complicated than it sounds. It can be done, but most find it easier to use ATI's DVI-to-Component adapter.

I assume it would be for 99.99% of the people out there too...but hey, this is just another hobby to me. :)

I use HTPC but its a little different than yours, I use the VGA to power a projector on 100 inch screen and its really sad how close DVD can get to an HDTV source.

Just imagine what we'll be making HD-DVD look like. :)

So, do a price comparison on a good PS-DVD player versus your HTPC.

Well, it's kinda irrellevant to me since my "HTPC" is also my primary computer...but you can build a decent HTPC for the same price as a high-end (bit better than pro-sumer) dvd player and the picture quality will wallop it. All you need is an OK processor (2GHz+), soundcard with digital out, and a low-end Radeon with the component out dongle (or VGA out to a projector like arod).

I am going to post some comparison screenshots of my own tomorrow (pre and post ffdshow).

if you do endup doing htpc, ffdshow is a must. I use mine with theatertek (never really got used to zoom player as there is too much stuff there for me to try and learn), plus you can get a HDTV tuner card for 150 and use that as your HDTV recevier as well. FYI, I have to use reclock as well and really everybody should have it installed as it doesnt screw things up if your not having problems.

Im actually going to be going to a dedicated HTPC in my next upgrade as Im ordering a AMD64 3000+ for my new desktop and moving my current (AMD 2000+) into the video closet and will control it via my pronto remote which is a new program I am going to have to learn but thats what Ive got the christmas break for.

Im actually doing quite the upgrade this christmas season as everybody I know gave me cash because they know I like to buy my own things. Getting new speaker wire and wiring for everything, a new dish HDTV receiver and a new Sound Receiver (yamaha RX-V1400, YPAO should kickass), all ontop of the new computer and dedicated htpc with usb-uirt so I can use my pronto to control the system.

Here are some comparisons I did up (pre and post ffdshow):

The difference is subtle but incredible once blown up. Look at the finer details...hair, clothes, etc.

I do the same thing with my HTPC. I use a home made vga->ypbpr cable and it looks fantastic. I currently run it at 856x480x32 @ 1080i timings and you can read eveything and it is crystal clear. It works great for divx.

Another thing...to output above 480p you have to disable macrovision. You can do this in one of two ways:

1. Rip DVDs to the hard drive (removing macrovision in the process)
2. Use a program such as DVD Idle or DVD Region-Free which disables macrovision on the fly.

When are we going to see MPEG4 DVDs? Is that HD-DVD? Have they worked on a standard yet? (ie WM9, or Sorenson)..

The Indiana Jones clip however, provides results that both a videophile and an evening movie enthusiast will enjoy.

I was thinking of making a home theater setup that uses my whole wall as the screen, buy some of that material you put on the wall with a fram around it.
The problem is I am not sure where to start with it...what projector, specs, etc.

I do know that I have a Dell SFF Optiplex system here..its only like 16" x 18" or so, once I get time I am going to set it up as my Audio system, put all my MP3's on it, then run a tv out card to the TV to run it with wireless keyboard and mouse combo unit.

I didnt pay for the PC, so it would be very minimal to me to make it.

how big is a "large screen" for you? You mean your 50"? I doubt I would notice it on my 29" TV.

A BenQ 8700 is a good choice.

Now, what are you willing to pay?

The benq is def nice but its a min of 5 grand, for somethign a little more modest the Panasonic AE-xxx series are very good. I have an AE-100 (the first one) and you can see pics ive taken in my sig, the pics suck but you cna get a pretty good idea of how much detail you will get (which is pretty good)
