I would not recomment to use a PC-Emulator like Virual PC, er Virtual PC because it will be very slow. Buy yourself a windows machine, this will be cheaper than Adobe Premiere.
Edit: Yes I know, its called viral, not virual ...
you could "aquire" final cut pro with limewire
or, if you've gone to OSX, use poisoned... its a gnutella, fastrack(kazaa), openFT and giftd client that kicks arse... and its freeware!
