Icecast - May 2009 - Newbie question: Poor transmission quality

I am using Icecast2 with Ezstream, sending a playlist of mp3s.  The signal
quality is fine over my home network; but out on the internet it is poor,
with frequent interruptions and losses of connection. 

I would like to know which of the following two conditions, if any, can be
causing the problem.  First, I have a dsl internet service, with only 160k
upload capacity.  Second, my home network is connected to the dsl modem through
a router.

Any assistance would be greatly appreciated.

Sounds like network problems.

OK. It IS network problems.
- Let me guess, some of the files are 320kbit/s and you don't reencode? 
- do the math - not enough bandwidth -> fail
- Or if you reencode to a certain bitrate it probably is 128k or higher 
- The intartubez are not quality guaranteed. The path from A to B might 
not get all the bandwidth it needs. Or simply your upstream bandwidth is 
chocked due to overselling by your ISP.
- You might be running other things that need upstream bandwidth. - 
Torrenting/seeding the latest Ubuntu install cd?

Or a combination of all of the aforementioned.

Thanks for the quick reply.  Please bear with my newbie questions.  There are
no other programs requiring upstream bandwidth.  What is intartubez?  I
don't
know about reencoding.  The files were made with iTunes on a Mac running OS 9.2.
It made mp3s from audio files.  How do I find the bitrate of those files?

Thanks in advance,
Mark

Problem solved.  My isp doesn't seem to be interfering.  I eliminated the
router, but that didn't help.  You were right, however, about reencoding.
Once I got madplay and lame and put a reencoding section from the examples
files in ezstream_mp3.xml, the problem disappeared.

Thanks,
Mark
