I just upgraded my PowerMac G5 1.8GHz tower (2003) from 1GB RAM to

This machine should work fine with this. Fer crying out loud an
*iMac* works with iSight video and iMovie.
Run disk utility to check your disk(s), disk problems will cause
issues like this, obviously. Is your hard drive nearly full?
Consider installing an additional disk for just video scratch space.
I'm doing video work on a QS 2002 Dual 1GHz with FCE4, and am a
Newbie of sorts ... moved away from iMovie ... these are suggestions
that may apply to your setup in some way.
Must say, I envy your system, a bit.
Tom Wolski's "Final Cut Express 4 Editing Workshop" suggests this for
conditioning your system for video work (As best as I can remember):
1. Disconnect form the network (make a location that turns it off,
remembering to turn it back on before you Logoff or Shutdown your
Mac). Also turn off Appletalk. Don't have any internal devices/
connections available (modem, airport, ethernet).
2. Use a simple background for your Desktop (non-changing) and Switch
Off Screen Savers
3. Have a separate (from your OS) hard drive for the video files. Make
it an internal one ... USB externals work in bursts of data, and are
not good for video capture. FW externals may be ok, not sure.
4. Redirect FCE4 to use the additional drive as a Scratch disk also.
5. Set Software Update to not check for Updates
6. Set your monitor to be displaying Millions of Colors with a minimum
of 1024 x 768
7. Energy Saver should be set so the system never goes to Sleep
8. There's something about Exposé and Spaces that suggest changing
keyboard shortcuts, but you'll have to get a copy of the book (pg
7) ... too much detail for me here.
Make sure your OS partition has enough room for your OS X to
breathe ... and I'm not sure how much that is ... using a scratch disk
for FCE4 solves much of that for FCE4.
iMovie 7 and 8 have a reputation of losing sync between audio and
video. I found 5 to work under Tiger, and I hear 6 works fine.
I switched to FCE4 recently and bit the bullet on its learning curve
(and additional price).
here's an Apple Support link showing more references foe help (Izzy's
video page):

Folks on the Pro Video Apple Discussion seem to be really helpful,
too ...
