After testing and checking the code as best as I could, I added Andrew's 0001-Add-hidden-fast-slow-playback-preference.patch (mostly) into GIT.  It is a very creative and nice solution.  Additional testing by others would be helpful.

you probably can safely git checkout this file back to original (current git) state.. I do not think Andrea's test showed any improvement in openability of resulting edl.. 
I left this out as recommended. 
 
so i wondered if changing speed for fast/slow reverse and normal playback was possible..0001-Add-hidden-fast-slow-playback-preference.patch

after few hours of hacking I made this patch. 

it makes fast/slow playback speed configurable in Cinelerra_rc via new stored variables:
 To test add the following lines to $HOME/.bcast5/Cinelerra_rc with the value of speed that you want.
SLOW_SPEED .2
FAST_SPEED 4
