Help Needed! DVD SP2 Crashes on import.

Hi, I have a new G5 Quad and transfered over all my apps, docs and settings from my TiBook with the migration assistant. DVDSP2 was working fine on the TiBook, but now it crashes any time I try to import an asset. I have a new m2v file from FCP five and it won't accept it. I have an old DVD project that I transferred over and it crashes when I try to open that also, even though it still works fine on the TiBook (but a lot more slowly!)

I have read through numerous threads on this forum and followed all the procedures, trashing prefs, receipts, reinstalling pro app support 3.1, etc., nothing seems to work. I know it's an old version, and I don't have the disc to reinstall it from scratch, but if it works on the TiBook why won't it work on the quad?

Please help -- I have a doc that needs to go out to to a TV station soon!

Many thanks in advance....
