    Hi Jon,

    Difficult one this. I had a 450 and I thought it was very good for the money.

    However, Davis have recently pulled out of making projectors ; they have "reassured" customers that spares will be available for "at least 5 years". Make of that what you will....

    You also need to be immune to the DLP rainbow effect (look at a white object on a dark background and move your eyes - you may see red, green and blue flashes).

    How much have you seen one for ?

    The 450's anamorphic mode is the same as all 4:3 panel projectors - it has to throw pixels away to unsquash the anamorphic picture. One good solution is to use an anamorphic lens to optically unsquash it so that you can use the full 4:3 resolution of the projector and not loose any pixels. To do this you run the DVD player in anamorphic 16:9 mode but the projector in 4:3 mode. The lenses unsquashes the image instead of the projector. I've hear that the 450 works well with HTPCs as well.

    I think the anamorphic lenses cost about £800 though - not cheap.... (Gordon, this sound right ?)

    Marata Vision in London are looking at doing the ISCO lens for this purpose. I suspect it'd be double that price though.

    I'd expect Tiberious should know the cost of a Panamorph as his must be near the top of the list by now.

    The biggest issue (IMO) with most of the Davis projectors is their internal scaler. 4:3 looks OK but 16:9 suffers badly with jaggies. Its particularly noticable with NTSC 16:9 images.

    However, the DL450 combined with a good scaler (Quadscan Pro or Quadscan Elite) can produce some remarkably good images.

    I have used the Davis Cinema One with a Quadscan Pro to good effect. I ran some 16:9 NTSC on to an 8ft wide screen and the quality was very good for the money, although the projector/scaler combination was a little tempremental. Later versions of the Quadscan Pro had software tweaks to help the projector lock more reliably.

    I can't comment on having the 450 modified to accept prog' scan, but would suggest you consider buying a Quadscan instead of the Pioneer. It will make all your sources prog' scan AND handle the 4:3/16:9 switching which simplifies your projector choice immensely. If the 450 is cheap enough then this would be a good combination.

    Good luck

    Thanks to everyone so far.

    GaryP - am demo'ing it tonite, i'm curious to see if I notice this rainbow effect.

    Chris Frost - what is the difference between the Quadscan Pro and the Elite model, the specs looked quite similar to me (do these bring about major improvements).

    Is it poss to get the Davis upgraded to prog scan? or anamorphic?

    What would be a decent second hand price, i'm still trying to sort out a sensible price on it?

    The Elite Quadscan is a board re-design internally to solve a banding issue on composite and s-video sources. It also has switchable filtering to improve picture on fixed panel projectors and much better/faster lock on to video source material.

    With the older PRo model when you wnet from s-video to Component or Pal to NTSC material the pictuer would go a bit crazy as it tried to lock on to the new signal. It only did it for a few seconds though.

    The Elite also has a fan while the Pro uses the case for cooling an d could run quite hot. Although they are reliable devices. I think the fan was probably just added to increase customer confidence.

    The DL450 used with a HTPC really rocks, I defy anyone to find a better image for the money. I am using one with a Greyhawk screen and should get a panamorph this week. I have however changed to a Plus UP1100 XGA projector recently which is also worth looking out for. If you are really interested and live anywhere near Wapping then drop me a line and come and see for yourself

    I would also say the DL450 is great when used with a HTPC.<br />The Davis internal scaler is Pants, but give it a good 800x600 picture from a HTPC at about 72Hz, and it will look superb.

    I use the Cinema one with my modified Mpact card,

    <a href="http://www.avsforum.com/ubb/Archives/Archive-000004/HTML/20010420-12-005121.html" target="_blank">http://www.avsforum.com/ubb/Archives/Archive-000004/HTML/20010420-12-005121.html</a>

    and the picture is fantastic.

    <br />PS. Danny, Did you get that capture card in the post?

    When you get that Panamorph installed, please mail me. I think I will be going for a long drive down to Wapping <img src="smile.gif" border="0">
