Do you really have to ask why a piece of equipment that costs $740 works
better than one that costs $30? I know the concept of "bargain", but
really...

You're converting a 625-line picture, 25-frames-per-second stream to a
525-line picture, 30fps stream. This requires RAM and interpolation. The
quality of the result depends on the amount of memory, the available
computing power, and the skill of the programmer(s) behind the product,
all of which presumably cost money.

If you can remember what professional broadcasters delivered from PAL
sources just a few years ago, even the quality of the CyberHome is
astoundingly good. In fact, it's probably the high overall quality that
makes the jerkiness of the picture stand out.
