Saving a m3u8 stream

[decibel83]

Hi.
I'm trying to locally save a m3u8 stream as TS file with the following command:

vlc -I dummy http://goo.gl/zW1gn --http-continuous --sout file/ts:output.ts

(http://goo.gl/zW1gn is a URL shortener for http://rrr.sz.xlcdn.com/?account=classe ... ylist.m3u8).

The stream is correctly saved, but I'm getting a 30 seconds file even if I exit from the command after 2 minutes, for example.

I searched for this problem, but I didn't find anything useful.

Could you help me, please?
Thank you very much for your help!
Bye.
