I don't propose to swap out footage based on looks alone - not using original footage at the start means that there is more to work with later for the the proposed attack scene without repeating visuals.

I've had an idea about the matte lines - they are pretty thick, If i get decent results I'll post details.

I also had an idea for a simple fix for the teleporters but I'm not sure if it's do-able. I don't have my TMP dvd atm as I've loaned it to a friend. Once I have it back i'll see if it's easy enough to do.
