I was wondering what does it really do? Does it upscale or convert standard DVD video to HD or better quality? Anyone
Thanks.

The basic rule of video editing is that you can never improve the quality of the original video. You can improve the way it looks and plays presentationally, but the actual quality of the video can at most be maintained at around its original level, or more usually degraded either a little or a lot, depending on the settings used.
In the case of upscaling to pure HD format, the same rule applies, though at least you should be able to preserve the original quality level if the video started out as high quality standard definition. But you can't miraculously transform the quality into true HD quality, if you see what I mean... You know the old saying: you can't make a silk purse from a sow's ear...?
As far as I can see, it is a bit of media-style hype. First, to be able to even appreciate it in HD format, you have to have some means of playing it in that format. You can play it on your computer, of course (note, however, that AVCHD high def format, if that is what is used, requires a Core 2 Duo or Quad to play back smoothly). Otherwise you need Blu-Ray rated equipment to either burn a Blu-Ray disc, or else play back a hybrid AVCHD disc burned on a standard DVD. Such Blu-Ray rated players are available on the market, but are still expensive. A useful part of this collection is the versatile Sony PlayStation 3. And of course you need a high def TV to see the results fully. But if you already have a HDTV, then you only need to watch the many programs filmed in SD to see what I mean. In many cases, such SD programs look pretty awful on a HDTV because the upscaling emphasises, rather than hides, any defects in it.
True or 'pure' HD as far as I am aware, currently means a resolution of 1920 x 1080p (p for progressive as opposed to i for interlaced). Upscaling to this format can also apply to HD video filmed on a camera (or captured from a HDTV) using a lesser frame size such as the common 1440 x 1080. But even with this, the upscaled video in effect has to add 480 pixels horizontally which in effect are invented out of thin air. I just cannot see that you will improve the quality of the original video by doing this.
And in effect, I have a Canon HV20 which uses the 1440x1080i format, and I leave it at that throughout my editing and production of a final edited video. I play it on a PlayStation 3 connected via HDMI to my 115 cm LCD HDTV which itself is true HD (1920 x 1080p) and has the capacity itself to upscale whatever source is put into it (either an SD DVD or my HD videos) to that full HD format. The result, particularly with my HD video, is excellent. Indeed, I have difficulty seeing any difference between it and true 1920 x 1080 video from a Panasonic S9 AVCHD camera sent to me by one of our users here... However, I am sure there is a quality difference -- it's just that my eyes can't perceive it...
