Well they are paid to make it happen, so if it is a little bit more complicated means that they have a stable job for a few more month
. It would have been good for them if the animation programing is available, but honestly, with modern CGI I wouldn't mind some more dynamic effects anyhow. As it wast stated before, we love DS9 for the story not for the effects, so if in a release we would have some original effects up-converted (Firefly had up-converted effects and were OK) and we could get a set of new HD effects like in the TOS blu-ray discs I wouldn't mind at all, as long as this would be used correctly and not abused. There were some generic shots re-used several time and could be updated/changed through new CGI effects.
