Problem with dragging in a sequence from Interplay and duplicating it, in order to revise the sequence.

Dragging in a complete (shortform MPEG50-SD) sequence from Interplay into a day-of-project, in order to use this seq. as a template and revise it.
Once seq. is duplicated (we  must duplicate the seq,so that the pointer to the original/former seq. remains pointing to the orig sequence;we dont want to revise the orig sequence).
Now,we revise this duplicated sequence:
Example: there are 2 promos in the sequence over a background. We only want to change ONE of the promos,the other will stay the same. Perhaps the background will change,perhaps not.
So:we place the new promo over a new background. New promo is moved back in a box (using 3DPIP),this promo's video layer is stepped into and a title tool visual tag added over the promo. However,when the title tool fades up in the box,the dissolve SHOWS THE LAYER UNDERNEATH the nested layer during the dissolve. Not to mention: when this occurs,now the ENTIRE :30 promo (which has this PIP placed on it) is transparent with the layer underneath the nest!! (Basically,V1 is background, V2 is nested: promo pushed back with title tool over it).

A workaround is having to replace  THE OTHER PROMO's video you are NOT changing in the string, and all of a sudden all the transparency goes away! BUt this is extra work we really don't have time for over and over again.

I tested doing the unthinkable: duplicating and then bringing this SAME ORIGINAL SEQUENCE in to our day-of project through the dreaded "file-open-bin" method,.rather than through Interplay...and NONE of this happens! NO wierd transparency or see-thorugh from the nested-in layers to the layer below. To me,it seems that this problem only occurs when dragging in a seq through Interplay and revising it!

Anyone see this before?

Rob:

I work with a lot of "Common Elements" master template sequences to do episodic shows and I have determined that if I standard drag the template sequence out of interplay into a specific project, all editing done in that sequence will be written back to the template. If I control drag, forcing a copy of the sequence, the original template sequence remains unchanged. But I have not experienced the transparency anomalies you are having.
