I can only get one EXT source working. This is what my channels.conf looks like:

NasaTV Public;IPTV:1:IPTV|S0P0|EXT|iptvstream.sh|1:P:0:2:3:0:0:1:0:0:0
NasaTV Media;IPTV:2:IPTV|S0P0|EXT|iptvstream.sh|1:P:0:2:3:0:0:1:0:0:0
NasaTV Education;IPTV:3:IPTV|S0P0|EXT|iptvstream.sh|1:P:0:2:3:0:0:1:0:0:0
Shine TV NZ;IPTV:4:IPTV|S0P0|EXT|iptvstream.sh|1:P:0:2:3:0:0:1:0:0:0
ROMA UNO;IPTV:5:IPTV|S0P0|EXT|iptvstream.sh|1:P:0:2:3:0:0:1:0:0:0

The corresponding unique numbers relate to the various URLs in the iptvstream.sh :

case ${PARAMETER} in
    1)
        URL="http://www.nasa.gov/55644main_NASATV_Windows.asx"
        ;;
    2)
        URL="http://www.nasa.gov/145590main_Digital_Media.asx"
        ;;

etc

I gather I've got this channels.conf wrong?

Each time I change to one of these channels, I get the first one only. ps -ef | grep iptv gives me:

vdruser 24107 17778 0 06:53 pts/1 00:00:00 /bin/sh /media/video/vdr-1.5.15/plugins/iptv/iptvstream.sh 1 4321

Also, I get no sound - but I'll look at this once I can change channels!

Thanks

Simon
