ok, 50+ looks and no answer? I must have not given enough info. when I try to open said video it just gives me the "this attachment cannot be viewed on this device" it is the same kind of device on both ends? I know when you send it to a computer you have to convert it from 3gp? to avi. or use quicktime.
do you have to convert it on your bb? seems strange if the answer is yes.
