Thanks for this interesting post - I was the

one you mentioned above who saw a friend's MOST

impressive HDTV front projection system (that looked

nothing short of truly amazing on HDTV material, and

MUCH better than anything I had seen in stores),

with very good display of wide-screen DVDs, soft

but acceptable display of SD broadcast material,

and HORRIBLE display of my SD-D25 Mini-DV material

(with "S"-cable direct-connection into the front

projector). What was amazing to me was that the

above was true, yet ALL of the better-looking

material had lower data-rates, and all but the

HDTV had lower resolution. I also have seen my

Mini-DV material displayed large on SD gear with

it looking good (and I'm well aware of the range

of "nasties" D25 is capable of showing - see:

www.David-Ruether-Photography.com/vid_pict_characts.htm).

I was willing to call this a conversion problem

with this particular projector (or with

resolution-halving projectors in general...),

but your post (and John Dyson's, above) made me

wonder again about this issue...

Sigh...

More on this?

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I can clearly state (demonstrating with my own video equipment), that DV50

type formats (50mbps versions of DV) look alot better on HDTV than DV25.  It

is possible to partially clean-up the DV25 picture, but the damage done by

the compression scheme is impossible to totally remove.

 

Even with OTA NTSC, if you look carefully, and have a fairly clean signal,

you can see the DV25 artifacts pass through.  BetaSP tends to have a soft

look also, but it is much easier to see the effects of BetaSP on SDTV

signals.

 

DV25 is still a really nice format for home use.
