Getting the core syste, taht comes with the standerd av cables. I own an infocus 4805 pj. Can I display 480p signal with the s-video cable.?? Or should I get the hd cables for the 360.

Many thanks to all.

Nope, S-Video cannot sustain 480p

Agreed, S-Video cannot output HD programming.

Technically 480p is EDTV.

Courtesy Wikipedia:

480p is the shorthand name for a video mode. The p stands for progressive scan, i.e. non-interlaced, the 480 for a vertical resolution of 480 lines, usually with a horizontal resolution of 640 pixels and an aspect ratio of 4:3; that is standard-definition television (SDTV). The frame rate (in the interlaced case the field rate) is usually 30 or 60 hertz and can be given explicitly after the letter. It is usually used in former NTSC countries (North America, Japan) for NTSC can have 480p30 image resolution, but analogue and interlaced. With doubled temporal resolution, 480p60 is considered enhanced-definition television (EDTV). It can be transported by both major digital television formats, ATSC and DVB, 480p30 also on DVD.

Apple Computer has recently released trailers it calls "480p" on its QuickTime 7 High-Definition gallery, alongside 720p HDTV trailers. Apple's "480p" appears to be a general term for 16:9 aspect ratio, 852x480 pixels, QuickTime 7 files encoded in avc/h.264. Interestingly, 852 is not a multiple of 16.

point is, S-Video will NOT output any sort of progressive feed. It is still too compressed a signal. If you've got an E or HDTV, grab one of the HD cables on the market. But like others said don't shell out the ridiculous amounts for Monster cables or what-not.

Im aboout to make a stupid comment... but does this mean that since my pj is native 480p, the s-video signal is going to be horrible, or worst yet, will not display???

Your projector will probably upscale the image to 480p, but the 360 will be sending a 480i signal. Since your projector has an S-video input it can obviously handle a 480i signal. You would likely get a better image using component or VGA if your projector has one of those inputs, but the S-video shouldn't be horrible or anything.

Once again... Thanks to everyone who took the time to answer my concerns...
You guys ROCK!!!!

That's not a stupid question at all. If your projector processes signals digitally, it will more than likely have motion blurs/pixel crawl. I know this is the case with pretty much every HD TV I've seen. Standard signals look worse on an HD than on a regular TV. Just shell out a little extra cash and grab some component cables.

p.s.
That site doesn't have X360 cables that I could find.

Go read the General AV FAQ (linked in my sig) which is pinned in the AV forum...

which is where this topic is being moved to right now.

Anything can put out a widescreen image....coaxial, composite, s-video, everything. YOu don't have to have HD to have a widescreen image.

I have that projector and I can tell you the following:

It works fine via s-video... but the signal is FAR less detailed. Not to mention the brightness of the signal when using component or vga is considerably higher. I found the s-video to be washed out to some degree when comparing it to component output (which is what I use).

Long story short... get the HD cables. You'll be a lot happier.
