Thanks for the heads up on that.  I've heard that NewTek has survived
admirably, and glad to hear they are still in the video production arena.

However, as you probably well know, doing anything for a small
non-profit convention requires scraping the bottom of the barrel for
equipment.  That's what I love about Linux so much.  Not that it's the
bottom of the barrel, but I can use bottom of the barrel equipment and
still get good results.  Not to mention this is the first time anyone in
our arena has tried something like this, so I figure the time and
difficulty of figuring out a solution is half the fun.

Yea, I'm going to do some DV capture of a few educational events in the
next couple of months and play around with a spare Duron (1G) machine I
have laying around.  See just what kind of loads I'm going to have to
deal with.

I had to figure as much.  I guess I'll have to play with it some.  I've
got a friend who's wiling to lend me a with a Hauupage (sp?) 350 to do a
true capture via standard video input, and I'll be interested to see
what kind of lag time I'll be running with it.  I've got to deal with a
seperate audio stream as well, so I've got good times ahead. =D

Thanks for the suggestion, and keep up the good work.  We need more
companies like NewTek around.
