    I had the opportunity to compare a Sony CS2 and a Sony CX1. I chose the CX1 because of what appeared to be better image [less chicken wire effect]

    However, on some DVD's this is not so. I guess it's because of the extra vertical pixels? It often gives a "blurry" effect.

    My question is, is this a "querk" of a particular disc [the poor one is "Goodfellas" [flipper], whilst Men in Black is excelent.

    Is there anything I could insert between my DVD and Projector to "enhance" the signal.

    I use a SVHS connection, would RGB be better.

    thx in anticipation

    Ive tried the Svideo connection and to be honest the VPL-CX1 svideo inputs/composite inputs were'nt really designed to be used unlike some of the specialised 'video' projectors. The difference in quality from the DSUB PC connector compared to the SVIDEO input is like night and day.

    To be honest I get a better picture with my VPL-CX1 than a recently tested InFocus LP350 DLP XGA projector which cost 4x as much.

    If you have a spare old PC (P3-500+) with a DVD rom drive (50 quid..) then I seriously suggest you trying it out (perhaps with your current pc..)

    I forgot to add that the main reason why the SVGA projector might look less blurry when using the video inputs is because a projector has a native resolution (SVGA 800x600 or XGA 1024x768 etc). If the input from video which is 752x576? then obviously the cheap and nasty internal projector scaler does'nt have to do much on the SVGA projector but on the XGA projector it obviously stretches the picture more I think...!

    However if you use a HTPC at set the resolution to 1024x768 from the PC then you will have far higher quality picture output...

    p.s sorry for the rush but off out in a bit!.

    Thanks for the comments..I have often thought about doing this.

    I have a laptop with a DVD, so I will try it tomorrow.

    If I go this route, how do I connect all other video sources, i.e. sat, video etc. What about sound?

    OK I`ll explain my setup, although if your buying PC parts you may want to look into the Fortissmo? sound card as that probably has better output for DTS/DD, I just used my old PC when I bought a new one for my HTPC. At first I used a laptop but these days you can pick up a Duron 900mhz/256mb RAM/Ati Radeon SDR 300W psu etc for about 250 quid or lower.

    I just built a PC for a friend actually which seems very stable and is'nt based on the VIA chipset but the SiS chipset. It seems a great motherboard and the system was incredibly cheap. The only thing though is with AMD chips they need to be cooled unlike my P3-550mhz old CPU's who work fine just with a large heatsink. Anyway...

    My old PC is acting as the HTPC for now with the following

    Dual p3-550mhz with just heatsinks (no fan) so this computer in the living room makes far less noise than the video recorder.

    256mb RAM which is the minimum for a HTPC imho.

    Windows XP although some prefer Windows ME for their HTPC.

    ATI All In Wonder Pro AGP 32mb however just get the Radeon SDR 32mb for your HTPC. I dont use the Video IN features of the AIW because dscaler does'nt support it so the WinTV card is used instead for this.

    WinTV Go! for composite video in (used in conjunction with www.dscaler.org for TV/Satellite/Cable to the projector)

    SBlive 5.1 which I plan to hook up to 5.1 speaker system or seperate amps.

    www.inmatrix.com zoomplayer for media and DVD playback using ATI video and WinDVD audio.

    www.dscaler.org free software which can use any of the BT8x8 chipsets from cards like the WinTV range to scale source images to any resolution you require with effects such as noise reduction/comb filter/gamma filter etc. TV on my projector looks just as good as my Sony TV but 90" wide, and that's no joke. However dscaler is very CPU intensive so I would go for at least a 900mhz CPU or if you have the money then 1.2ghz+ but imho dscaler works great at 1024x768 under Windows XP with dual P3-550mhz cpus.

    I have cable TV (Pace Digibox) which has a scart lead coming from it to the composite IN on the WinTV GO! (30 quid!) card and the quality is fantastic in conjunction with http://www.dscaler.org . Also the latest WinTV software uses some of the code from dscaler for its WinTV 2000 application and the picture quality is very good now even without dscaler. The scart lead's audio just connects into the line in on the sblive 5.1 sound card which all cards have, I just mute LINE IN by default unless we want to watch TV.

    Im using a Creative DVD drive which is pretty quiet. A good source of information is www.avsforum.com under their home theatre PC section. Using the search function you can learn a lot about other peoples experiences with different sound cards etc so its worth taking the time to read.

    Any questions fire away!

    I forgot to add that the HTPC also acts as a great music jukebox if you rip all your CD's to MP3 format. We can select any type of 'mood' from a menu for example christmas songs :) and it will play through our hi-fi.

    Can't wait when someone makes a very powerful tivo style box which can do all of these things although as ever with HTPC's people tweak them and upgrade components to give the best combination and versatility.

    aha just been looking at someone elses home cinema and he's using this great little motherboard I used to build a PC for a friend. I believe it goes up to 2ghz AMD XP CPU too!, and costs about £55, complete bargain imho.

    http://home.attbi.com/~lynxfx/equipment.html

    down the bottom lists the motherboard :), think I might buy one myself if I can find a really quiet fan for say a 1.2ghz athlon :).

    Many thanks...I am convinced.

    Will try it with my laptop tonight and then start work on my PC.

    My current PC has a DVD player, SB 5.1 plus a Radeon 8500, so has all the right stuff, plus I do have a couple of TV cards lying around. [never had a decent signal, so never bothered]. CPU is Thunderbird 1.4 GHz, so again no problem.

    I have a Sony DVD player [just had it upgraded to MR, never mind].

    Thinking it through, it might be possible to use the dual head functionallity of the RAD8500 such that I can have one display going to the TV and the other to my projector [possible?] thus allowing me to get away without a monitor sitting in the front room.

    I am still anxious to use my Sony AMP [1070], so I am going to look for a sound card with optical out. I really like this AMP.

    Of course this all means that I will have to build myself a new gaming PC [wife won't let me game in the front room ]

    :D

    again many thanks

    Pete
