FIX FIX FIX FOUND!!!
OK, I was severely pissed when this happened to me but I found out how to fix it... or at least how to avoid it.
I at least had one saved game from early on...
My progress was Telos -> Dantooine ->Nar Dashaa (spell:P) -> Dxun....
My old save was from Nar D'y.... I hated it because I was already a Sith Lord and I had to lose a lot of levels... what I did was I completed Nar Dy again then instead went to Korriban, so I made Dxun my last stop (I went through all the other planets to finish off any left over quests)...
then when I had to go to Onderon, I added the alien dude (forgot his name, -bionic arm) to me and Mandalore...
I finished that, came back, and had no problems, all the cut sceens worked!!
FINALLY, I hope theres no more bugs like this... ugh!
:D
Well, hopefully this will help some of you and not force you to have to start over!
