[MPlayer-users] Can't dump dvbt stream on some channels

[Stefan Sassenberg]

Hello,

I usually record dvbt streams successfully with the command
mplayer dvb://"channel" -dumpstream -dumpfile 
"/usr/local/share/multimedia/movies/new/dvbt_watch/timestamp_channel.stream" 
run by a bash script.

But there are four channels that do not let me record the stream. 
Mplayer breaks with the following output.

MPlayer interrupted by signal 15 in module: dumpstream
---------------------------------8<-----------------------------------

There's always a file of 4096 byte size dumped. I put a sample into the 
incoming dir on the mplayerhq ftp server, the name is 
081214_191010_MDR_FERNSEHEN.stream

When I execute the command outside my script it does not return but also 
does not record a stream. It only dumps a few hundred bytes per second.
When started with -v the output ends with
---------------------------------8<-----------------------------------
SUCCESSFUL EXIT from dvb_streaming_start
STREAM: [dvbin] dvb://MDR_FERNSEHEN
STREAM: Description: Dvb Input
STREAM: Author: Nico
STREAM: Comment: based on the code from ??? (probably Arpi)
---------------------------------8<-----------------------------------

When started with -v -v the output continues

Can you see what's wrong?

mplayer was compiled with "./configure --disable-x264 
--disable-x264-lavc" and is running on a gentoo 2008.0. I had to disable 
x264 due to a compilation error.
