However, the popping is gone, and when I select a section to render, the

the .avi file to .dv using ffmpeg. I also used the same time marks in
the .avi file, that the popping noises existed in the converted .dv
file. The only difference is I'm using the unconverted .avi file
instead of the converted .dv file. So to sum everything up, we've fixed
several issues, but have a seemly "benign" intermittent error message
that all one needs to do is click okay and continue.
I may know what your problem is. DV format handling in Cinelerra-cv had
such popping noises until some stage in the last 12 to 18 months when
this problem was fixed (by Richard Baverstock I think). Putting the DV
into a container format such as quicktime/mov or avi was the known
workaround to avoid this popping prior to the dv bug fix being committed
to svn. Any new cinelerra-cv version shouldn't have this problem.
Personally I now find 'native' dv format very convenient to work with -
and I have an cinelerra-cv checked out from the svn some 6 months ago.
From what you are saying above - you might attribute the popping to the
ffmpeg conversion from dv to avi/dv - but actually the issue, in the
past, was with Cinelerra-cv.
So you could conclude that, for cinelerra-cv, dv in an avi or mov
container is handled by a different back-end than straight dv.
Basically I think cinelerra has its own dv handler.
I don't know if you are using cinelerra-cv or cinelerra from heroine
virtual. It is possible the the popping fix never made it upstream to
cinelerra- HV - I wouldn't know.
If you have a new version of cinelerra-cv try one of those old dv files
and you might find it is now working perfect.

This is a very annoying bug even if 'benign'. I come across it all the
time. I'm pretty sure it is well bug-reported.
I wouldn't worry removing your pulse audio support unless you come
across actual problems in your own setup. Fixing problems that are
there is troublesome enough!
High Quality FOSS video editing is history in the making - I like to use
and watch Cinelerra and the Lumiera project because something really
exciting for the whole world is coming together here. I do sometimes
wonder what I might be achieving if I instead focussed on productivity
(by using FCP) - but, for one thing, that would require me to pirate and
crack software and I find the whole experience demoralising.
