They may well be able to convert interlaced to progressive.

I don't think those engineers over in (whatever country) thought of that,
or
had the freedom to do what they did think of.

I switched to LCD about a year ago, home and work.  I kept the old monster
CRT display just in case.  At this point I'm sure I'll never use it again.
Now I have 2 of them sitting around.  One is a Sony with HD-15 and the
other
is a Sun with 13W3.
