ERROR: Last tag size must be greater/equal zero

Wed Mar 16 09:50:56 EDT 2011

hi all, I just got an annoying problem with this, RTMPdump just stop
working accidentally in my bad internet connection. When it happens,
windows just prompt "RTMPdump.exe is stop working". After that,
get_iplayer can not download the program continuously. It will stop at
"ERROR: Last tag size must be greater/equal zero", but when I use
option "-o" and indicate a new output location, it works again as the
program redownload form the beginning. I've tried two computer, found
the same situation (one's XP, another 7).

any helps are appreciated.
