Rtmpdump fails half the way through

[naskoboy]

Hi friends,

I spent few days trying to capture this stream and I am exhausted.
Pls take a look and let me know if you have any idea what is going on.
Original link of the stream is http://tv.bnt.bg/bnt1/16x9/
however it's restricted only on territory of Bulgaria which I managed to overcome via a socks proxy.

RTMPDUMP debug session is attached as a file.
RTMPSUCK output generated from within Bulgaria is enclosed below.

Help appreciated.
