    I just got a new toy...an Electrohome ECP 4000 pj [​IMG] .
    I currently don't have the capability of sending it a progressive signal. For playing DVDs and with a tight budget (less than $500), would you recommend a HTPC (w/ descaler and power strip), a HTPC with a hardware card like RealMagic or a progressive scan DVD player?
    I will be using a 1.3 gain 4:3 screen that is 5' wide. Throw distance is approx. 7'6". FYI, the ECP4000 uses 7" tubes (Sony SD187) and has a horiz. sweep of 80 kHz. Does the ECP4000 need a RGBHV signal coming in or can it use the sync on green of a progressive DVD player? I want to know if I have to use the AudioAuthority box with a prog. scan DVD player.
    Thanx in advance for any thoughts.

    You can build yourself a HTPC for under $500, one that will do DVD as well as any other HTPC, and better than DVD-scaler combos at any price. Something like this:
    Duron 750 MHz
    SiS 735 Motherboard
    128 MB RAM
    15 GB 7200 RPM IDE drive
    Radeon LE
    Old slow DVD player
    Zoltrix Nightingale Pro sound card

    johank,
    your ECP is very easy to set up, and you can go as wide as 80" with a good image. The ECP likes 1.5 x width of screen for placement (to the green tube).
    Go the HTPC route, you will have more options for resolutions. you will need powerstrip 3.0 (shareware)for custom resolutions. I put mine together for less than 700.0 (w/o Video card)
    this site has a list for entry, mid, & high end HTPC components

    >>>... has a horiz. sweep of 80 kHz. Does the ECP4000 need a RGBHV signal coming in or can it use the sync on green ...
    All of the below applies.
    The projector needs multiple sweep capability (including 31.5 kHz non-interlaced for progressive DVD or 15.75 kHz interlaced for regular NTSC) to accept output directly from your DVD player.
    Either the projector needs multiple color space input capability, namely Y/Pb/Pr (which is approx. red/white/blue) as well as RGB, or the DVD player needs multiple color space output capability (RGB as well as Y/Pb/Pr) in order to accept output directly from your DVD player, otherwise a converter box in between is needed. COlor space, if selectable, is always done manually using a switch or menu choice.
    Check to see if your projector accepts sync via the green line. If not, you won't be able to connect most DVD players directly, I am not sure who makes a sync. separator box with RGsB (three lines) in and RGBHV (five lines) out. (The Y signal of component video uses the green line.)

    Allan, I was reading the service manual for my pj and it will accept a sync on green signal (FYI, AudioAuthority makes a component to RGBHV converter for under $200). However, I've decided to go the HTPC route to get a 720p 16:9 signal.
    Carlos, thanx for the link. I'm going with the ASUS CUSL2 mobo, an ATI Radeon vid card (which one???) and a Toshiba or Pioneer DVD-ROM drive. I already have a Philips Acoustic Edge sound card. I will go with an Intel PIII chip but not sure of the speed. What does the EB stand for with some PIII chips?
    Abdul, what are the advantages of the Radeon cards over, say, the GEForce2 cards?
    Thanx guys.

    The consensus is that the Radeon cards have superior video quality for DVD, particularly for high interlaced resolutions. Radeon cards also include a CD with the highest PQ DVD player (ATI Player) for free (though you'll need to download a more recent version.) Geforce 2 cards are better for 3D games.

    johank,
    Radeon has just released its new Radeon II video cards
    RADEON 7500 & 8500
    for info see: http://www.rage3d.com/
    prior to these new cards many were purchasing the 32DDR LE version for 70.00 and flashing the BIOS. you can now purchase the 64DDR version for 140.00 this card is good for your gaming needs. The 32DDR (std.) is approx 85.00.
    DVD ROM, try to get a region free Toshiba. The link that I left you has a "BEST IN CLASS" link, their is more info available with specific models to region free DVD rom's

    Thanx Carlos. I have purchased a Toshiba 1502 DVD-ROM drive and an ATI Radeon 64MB DDR vid card. I also now have an Enlight desktop case.
    I now ran out of $$$ so the CPU/mobo/memory purchase will have to wait a week or two. In the meantime, I'm using a Hollywood+ card to play DVDs using a PII/400 machine (though the setup needs some tweaking as I write this).
    Thanx again.
