I was going to start asking Codec questions, but thought I better find
out if it was the system or me :-).

I am using a PC with WO.34b4 as you probably saw described before. This
is receive only, with a 28.8K modem.

I have a real problem with lots of bad squares and that they seem to take
forever to clear up. Pictures are very good for those sending with a
SUSTAINED 15-25 KBS rate. But everyone else comes through with lots of
missing/bad squares and it can take a minute or more for these to go away
at times. This even exists when the picture is not changing, at all, but
has a continuous 2-6KBS data rate. I assume the Codecs slow
re-sending static squares to conserve b/w, but what I see is ridiculus.

I realize this would be very subjective, but could someone comment on
what they see on a "proper" receiving system. I mean, a powerful MAC
running the latest Cu-SeeMe software and connected to the net through a
little used T1 line. I assume that would be the ideal. Do you get lots of
bad squares on pictures that average folks are sending on NYSERNET or
Cornell? Do they take a long time to clear up? Do you even see this
to a fair extent on NASA feeds?

Thank you very much. Dave in Phoenix
