Resize already encoded FLV?

hi, this is probably something basic but i couldn’t figure it out… is there a way to resize an flv? i have a client that gave me a set of FLVs that a previous designer made for him. the client no longer has the original mpgs. these flvs are much larger than we need them for the new site, and if i just resize them from flash on playback they look terrible and are an unnecessary longer download. i tried importing the flvs into flash’s encoder, flixpro and squeeze and haven’t had any luck. thanks for any help! :thumb2:
