Does anyone know a resource where I can learn about minimum system requirements
for Flash8 or later playback?

I encoded a video using FlashCS3 video encoder - and on most computers, it
looks just fine/as expected. Just to see what would happen, I tried to view it
from the web, on a Mac G4/867 that we have sitting around because it has PCIx
cards for SCSI in it... It is running OSX 10.4.11 -- Safari 2.x. It has 1.25
gigs of ram.

Video simply will not play back on this dinosaur (well, it plays, but 1 out of
10 frames, if I'm lucky - and audio is total sputter, it is unusable) ... ok,
this box is ancient. BUT must I assume all current web visitors will have
rocket-ship speed hardware?

Is there a guide that's been assembled with guidance? For video encoded with
VP6, do not exceed Y x Z dimensions at 15 fps in Flash player 8, etc... ????
I've searched...

Thanks in advance for any VP6 encoding guidance.

Bonus question: since I own CS3 and QTpro (Final Cut Studio), is there a true
benefit from Flix or Flix Pro (or another stand alone encoder)? My primary
machine for this is a MacBook Pro C2D 2.33. Thanks.

PS -- the internet bandwidth on this machine is superior... 10megs
downstream... on the same network (wired) as a few other (faster/newer)
machines that have no issue viewing my video. The video is ~72mb.
