Increasing movie dimensions...for free

[bittersweet]

Hi guys,
I have several movie clips that're directly taken from VCDs that I want to edit in Final Cut Express. Thing is, they're only 320 x 240 pixels, and Final Cut requires 750 x 480 to fill the entire screen.

I've heard Quicktime Pro can resize a movie, but I don't have money to buy that. So, is there another alternative? OR, is there a way that I can decrease the movie size of FCE just like Adobe Premiere (where I can choose Multimedia Quicktime size - 320 x 240)?

By the way, I use bbdemux to demux it, producing .m1v and .mpv (I think it's .mpv :wound: )
