help with this stream - always video frozen

[streamyliizz05]

I need your Help with this stream:

https://portal.stretchinternet.com/n...reamType=video

I try this:

rtmpdump -r "rtmp://o3.stretchinternet.com:1935/ondemand/" -a "ondemand/" -f "WIN 16,0,0,235" -W "https://neo-cdn.stretchinternet.com/assets/flowplayer.commercial-3.2.18.swf" -p "https://portal.stretchinternet.com/naia/portal.htm?eventId=224317&streamType=video" -y "ashford/ashford-224317-v.mp4" -o - | "C:\Programms\MPlayer for Windows/mplayer.exe" -cache 8192 -

The Video stops after a few seconds and i become this Info:

Cache empty, consider increasing -cache and/or -
cache-min. [performance issue]

I add --live

rtmpdump -r "rtmp://o3.stretchinternet.com:1935/ondemand/" -a "ondemand/" -f "WIN 16,0,0,235" -W "https://neo-cdn.stretchinternet.com/assets/flowplayer.commercial-3.2.18.swf" -p "https://portal.stretchinternet.com/naia/portal.htm?eventId=224317&streamType=video" -y "ashford/ashford-224317-v.mp4" --live -o - | "C:\Programms\MPlayer for Windows/mplayer.exe" -cache 8192 -

It works , but not good.
Every few seconds the video stops/frozen. The Sound sometimes stop with the video, sometimes works.
I become this Info:

Possibly bad interleaving detected.
Use -ni option if this causes playback issues and avoid or fix the program that
created the file.

...and again after a few seconds this....

18945.977 kB / 309.63 sec (3.1%)Cache empty, consider increasing -cache and/or -
cache-min. [performance issue]
18961.970 kB / 309.83 sec (3.1%)Cache empty, consider increasing -cache and/or -

18997.103 kB / 310.30 sec (3.1%)Cache empty, consider increasing -cache and/or -
cache-min. [performance issue]
19009.719 kB / 310.47 sec (3.1%)Cache empty, consider increasing -cache and/or -
cache-min. [performance issue]

than the video works a few seconds.......and than...again frozen and the Info:

Cache empty, consider increasing -cache and/or -
cache-min. [performance issue]

than the video works...frozen....works....frozen....etc.

The Sound stops sometimes with the video. Sometimes the sound works and only the video stops/frozen.

I have this problem only with the streams from this site!
I have no idea why. On the site itself the video are perfect.

I never had problems with rtmpdump/Mplayer! Only with the Streams from this Site!

Another Example from this Stream:

rtmpdump -
r "rtmp://o3.stretchinternet.com:1935/ondemand/" -a "ondemand/" -f "WIN 16,0,0,2
35" -W "https://neo-cdn.stretchinternet.com/assets/flowplayer.commercial-3.2.18.
swf" -p "https://portal.stretchinternet.com/neoPlayer.htm?eventId=224317&streamT
ype=video" -y "ashford/ashford-224317-v.mp4" --live -o -   | "C:\Programms\MPlayer for
Windows/mplayer.exe" -cache 8192 -
