I have already thought about this. There must be instructions to switch the 
processor mode, but it is possible that those are privileged (someone should 
look that up). And then there is still the problem that the data to process 
might be above the 4GB limit in the adress space, thus being unreachable to 
32bit code. I guess the cleanest solution is to launch a 32bit helper process 
just running a simple work loop wrapped around the DLLs and use shared memory 
(if possible) or some other communication to move data between the main xine 
process and the helper.
