Mplayer detects that your stream is transport stream, which is what vdrrequires.

This is the pid information vdr also requires in the channels.conf entry.

This means that the stream is using h264 encoding.

The line was added by vdr when it detected that the stream is in the format itsupports. (Though I wonder if it shouldn't happen when disabling sid scanningwith S0.)
It also means that iptv plugin is working and the stream in rtp formatis really supported.
The entry contains 0 as the video pid which means that the channel is treatedlike a radio channel.

This is what xineliboutput does when viewing a radio channel. It's called thegoom plugin.

I think you are only missing h264 support from vdr core which could be thereason why the video pid of the channel is set to zero.
A patch for adding h264 support to vdr 1.6 -series is included in this mailinglist post: http://www.linuxtv.org/pipermail/vdr/2008-March/016227.html
It's the vdr-1.5.18-h264-syncearly-framespersec-audioindexer-fielddetection-speedup.diff.bz2and it works for 1.6 even though the name suggests 1.5 version.
Vdr 1.7.x includes h264 support by default.
