I've noticed these audio-less recordings too, I hadn't noticed that the 
seeking patch didn't work with them, but I have been wondering why they 
have no audio.

My current guess is, as you say, the extra audio channel.

Last year when I was experimenting with playing back Myth recordings, a 
large number of software players I tried (both commercial and open 
source) had issues with the audio channels on some UK DVB recordings.

If I reprocessed the whole MPEG stream removing the extra audio, then 
most things would then play it fine.

I notice that the PS3 does not let you select an audio track (although 
it does let you select Left/Right/Left+Right from the one you have) and 
I'm guessing that part of the DLNA specifications for playback of an 
MPEG-TS say you should only have one.

I'm not sure what to do about this at the moment, as I don't have access 
to the real specs to be sure.

Hopefully there's a few of us working hard at getting this working,
