for what it's worth, i totally agree. mpeg2 is fine and produces excellent
quality. i hear all this riff raff about HDTV and DV versus mpeg2, and
here's the rub . . the average consumer can tell the difference between sd
and hd but when there are four of them mixed, they cannot tell the
difference correctly. oh they will say this one is better than the other
but as far as the hd being the better one, they're not always right.
moreover, what's better is not necessarily cost effective. to pour a
fortune into making hd and watching hd for what appears to the average
consumer as about 10% better picture, is simply not worth it.
how perfect and pristine does one want to get. if your a video nut, then of
course pour all the financial resources into it, after all it may be your
hobby, but if your dealing in practicality, dvd is great. just the life of
it might be the biggie issue.
