 With 1080i MPEG2-TS, yes.  The 720p MP4 video from the Xacti only 
slows to about 2 fps for a second or so, then regains full speed.
I see this behaviour on an Opteron with four CPU cores.

 About time to nag about this bug.  It makes Cinelerra unusable
for HDV editing, and it is a regression.  HDV editing worked fine
already two years ago, on fast machines.
