have a look here: http://www.saunalahti.fi/~rahrenbe/vdr/iptv/
as far as i know, you have to change your channels.conf like this:
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|2:P:0:2:3:0:0:1:0:0:0 NasaTV Education;IPTV:3:IPTV|S0P0|EXT|iptvstream.sh|3:P:0:2:3:0:0:1:0:0:0 Shine TV NZ;IPTV:4:IPTV|S0P0|EXT|iptvstream.sh|4:P:0:2:3:0:0:1:0:0:0 ROMA UNO;IPTV:5:IPTV|S0P0|EXT|iptvstream.sh|5:P:0:2:3:0:0:1:0:0:0
have a look at the number after |iptvstream.sh|X
Thanks.
Looks like the streams I'm connecting to are the problem - various errors connecting.
RE: the no sound problem, I'm struggling to troubleshoot this as the Nasa Public channel is the only one I have - and there's often no sound anyway!
