For the record, I've just tested it, and while it won't cause a crash, it seems to randomly pick a player with FSS abilities, and always show them performing the Power FSS moves. This isn't surprising, as NBA Live 08 moved away from the concept and utilises that data field (and legacy FSS moves) a little differently than NBA Live 06 and NBA Live 07.
If you'd like to see some different line-up introductions and cutscenes though, Dc311 has previously uploaded the NBA Live 2005 scripter. Just backup your files before overwriting them, in case you want to restore them quickly and easily.
