-Fixed Metal Saga video (which i seemed to have broken with voodoo!! maybe i should see the lady in the voodoo shop, last time i did that she told me i had to fight a fearsome pirate...) ahem, sorry. 

-Fixed a Bitstream bug which was annoying me.
-Modified a silly long if check with multiple bit shifts, should be a tiny bit quicker.
-Various other IPU changes
