As of this date, most of the above mentioned programs will have trouble with justintv live streams, because
RMC 4 (
Jaksta) is using some sort of token.
Jaksta works about the best, but you must use rtmp record mode, and also you will have to repair the file afterward using jaksta's fix tool, setting the interval value to either 15 or 16 (I forget which).
StreamTransport will also work, but the saved file will need even more repair work than just setting the interval value. I've only been able to do the repair manually using several steps.
