    The following is excerpted from a post of mine in the Home Theater Software forum. It was suggested that I ask it here, which is obviously a more appropriate location.

    Hi Dan,

    I've got a BarcoG808s, so I don't know if this will help you or not, hopefully it will, otherwise I suppose it will just simply bump your post back to the top for someone else to chime in.....

    Anyway, to access the second modes, I need to change my input ie. with a 4:3 input, I'll use input 5 (or 2 if it's S-video). For widescreen, I choose 95 (or 92). This 9* mode is a second memory for the same input. You then take this 2nd memory and reduce your vertical size for it to the 16:9 (or whatever) proportions. Then, when you want to watch your anamorphic 16:9 DVD's, you go to input 9* and when you're watching (for example) television you switch back to your (ie 5 or 2) 4:3 setting.

    Hope that makes sense to you. It's probably not perfectly clear, but I'm trying to type this while dealing with my 4 month old boy. Good luck.

    Very interesting, thanks. Did you find that out through your own experimentation, or was it documented somewhere? I know there are at least 3 versions of the 708 series owner's manual (I've only read one of them), but I didn't see any mention of that sort of thing.

    Prathavan,

    You're my hero! [​IMG]

    I tried out what you suggested, setting the DVD player to widescreen mode and setting the projector to source #96, and WOW! Amazing what an extra 1/3 or so of resolution does. Scan lines were fairly apparent before, although not enough to be distracting, at a seating distance of around 9 feet with progressive scan in use. With the widescreen mode in effect, I cannot even make out scan lines standing ~4 feet from the screen (any closer and I block the projected image). Very impressive.

    I had to do some geometry and convergence work for the #96 source, which is to be expected. It appears non-anamorphic DVDs require me to switch the projector back to source #6, otherwise they get stretched vertically (still not the squishing that I would have expected). Interestingly, it didn't seem to matter if I left the DVD player in widescreen mode when switching between the projector's sources. Can't say I understand why that is... Fortunately, the projector appears to hold its settings just fine in memory when switching between sources (I've had it less than 2 weeks and hadn't tested that yet).

    Much appreciated!
    Dan

    Dan,

    Glad it worked out for you.[​IMG] I'm also glad you were able to decipher my earlier post. Re-reading it now, it seems kind of cryptic.:b

    If you're impressed with the PQ of the anamorphic squeeze with just a progressive DVD, wait till you hook up your PJ to either a scaler or an HTPC!!

    The wealth of technical information over at AVS borders on overwhelming... Yours was the first answer I've seen to this question, though. I'll have to check the other 708 owner's manuals and see if it's mentioned anywhere in there.

    Hey Dan,

    Well, I looked at my owners manual and I can't find anything about the "90 memories" so I must have garnered that tidbit from the forums. Still, I've read it often enough to know that it's fairly common knowledge, so I'm quite sure you'd have come across it sooner or later. I am pleased that I was able to assist you in coming across it sooner though.

    I agree with you (and the esteemed Mr. Lucas) about the sound experience, that's why I'm still using a scaler for the video only. Mine is a Quadscan Pro, pretty old by today's standards, but the pic quality is fantastic. I'm running my screen to 120" in 4:3 mode and whatever that works out to as 8' wide in 16:9. TV quality is still (comparatively) horrific (but MUCH better than if I switch to the non-scaled image - the old adage garbage in garbage out still applies), but DVD's look superb. You can probably pick one up pretty cheap these days.

    Having said all that, for a 7' wide screen, if you can't see any scan lines from 4 feet, there's no way you'll see them from your seating position, so just sit back and enjoy the show!! Save your money for HD.

    Welcome to the wonderful world of Front Projection CRT!!

    This is a bit off topic, but the topic is pretty much resolved, so what the heck... [​IMG]

    My gut feeling is that high quality, scalable DVD players will come along before HTPCs make up sufficient ground in their weaker areas. Time will tell...

    Probably my biggest surprise in working through the projector learning curve was stumbling across my Barco having a built-in line doubler. I had no idea that was in there! I only mention it because it somewhat makes up for low resolution sources, such as if I ever get around to hooking up my el cheapo super vhs deck. Not nearly as good as the progressive signal (which I found automatically turns off the line doubler), but still respectable. I imagine your scaler offers more punch, but it's better than nothing, right?
