I think the only way you can do this is to install the Perian QT component. That will allow you to open the flv in QT (probably Compressor and MPEG Streamclip, too). If Compressor works I’d use it. Make sure you select the highest quality choices in the encoder tab of the inspector. However, your final results may be disappointing as you’re starting from a highly compressed, fairly low datarate source.
