AVRatThat's not true - stand far enough away from ANY display and it'll look HD.
You will never get HD quality from anything less than 720 formatted material. The HD minimum spec is 720 pixel resolution in the vertical axis. Depending on the scaler involved, you can get very close. In other words, you must provide HD material to a HD display to get a TRUE HD picture.
The non-marketing version of what defines an image as high definition is that when you add one more line of resolution to the image, it doesn't appear to be one bit sharper. So - a 20" display, from 20 feet away, may not look any better to someone with 20/20 vision whether it is fed the VHS version of King Kong or the HD-DVD version.
But, marketing has warped that idea so that people overly tie the 720p (or better) resolution with the exclusive meaning of HDTV.
HDTV is about image size, image quality, display quality, seating distance, and room conditions, as well as some other factors I may have missed. Simply sending 720p HD source material to a compatible display may give a defined version of HD, but doesn't promise the best possible image.
Everything else is a cleaned up version - the best possible version really - of the lower quality format.
In order (pretty much) standard analog cable and VHS are about the worst original video sources. Digital cable and satellite (DirecTV/Dish) are next. Then DVD comes into the mix as the best non-HDTV source available.
Finally, we get HDTV from cable, satellite, and Blu-ray/HD-DVD disc formats.
So, what happens when you run a VHS tape through this machine? Well, you get a really big VHS image. It will look NOTHING like HDTV - but it won't necessarily look ‘bad’ or even ‘so-so’. It MORE depends on your acceptance of the quality. If you know VHS won't look great and aren't nitpicky, then it may look really really good - to you.
If you are picky, then they will look lousy.
It has been said, no less than 10 million times, that converting non-HD material, to an HD format does not make the original source material HD quality. But, this is moreso true with poor quality standard sources such as VHS tapes. This leads to a bit of not-so-typical sarcasm from our beloved Mr. DeBoer here. If he acts up again, just slap him.
I still have about 30 or 40 VHS titles - I am simply replacing them all with DVD titles at this point. In fact, I am thinking about selling or giving away my VHS collection this year. I'll try eBay first - then I'll donate them somewhere.

Sign me up for one of those new-fangled VHS deck thingies!! All kidding aside, you will not get HD quality pictures from your old analog video tapes.
If I get a SD-DVD player with “clean 480i” over HDMI can I get HD quality?
Sorry for the dumb questions but other threads are unclear.
:o loose tool :o
