Probably I do not quite understand what you are doing, but if you want to see the original media with no effects/autos, why not just "Open in new viewer" - you can do that for each of them?  You can select all of them in the Resources window, and open them all at once.  And, of course, you would still have your mixer windows.     gg/phyllis

I"m currently using cinelerra to master conference video's and am
overlaying slides and videos doing fades between the slides and several
video streams.

One of the things I'm really missing is a monitor of each of the tracks.
 I have been using the mixer windows, but that only shows the post-mix
view so if the track is muted or faded to 0 I can't see whats showing on
that track.
