Flip Video to MPG converter

I am trying to load a MPG video.
Is this possible?
If so how?

I tried a converter to FLV however, it loses quality.
Is there a converter that will not lose quality?

Thanks,
Tony

@Tony - The player will not accept MPG. You should convert it to MP4, and encode it in H.264. - http://www.longtailvideo.com/support/jw-player/jw-player-for-flash-v5/12539/supported-video-and-audi...
