this one is the only one with a PAT/PMT pair. When pids are clearly 
typified
there's no problem whatsoever: all the payload is fed to the decoder and no
crc error is present.

there's no PAT/PMT.

Long time ago, when I first realized that auto-detection can fail,  I 
forced the
dvb:// code to always include pid 0 (PAT) to the TS and added to the xml 
doc:

[...]
~.mplayer/channels.conf
[...]
<para>
 In your audio and video fields you can use an extended syntax:
 <option>...:pid[+pid]:...</option> (for a maximum of 6 pids each);
 in this case <application>MPlayer</application> will include in the
 stream all the indicated pids, plus pid 0 (that contains the PAT).
 You are encouraged to include in each row the PMT pid for the
 corresponding channel (if you know it).
 Other possible uses are: televideo pid, second audio track, etc.

How many people read the docs? :)
