Hi Stuart:  Thanks for your quick response - and, of course, for looking 
into this.

I don't know if other people have PS/HD material.  I don't.  My cut HD 
material is still TS, and plays via upnp with only minor glitches at 
internal cuts.

My PS/SD material is usually produced en route to DVD, and often quickly 
deleted from disk.  It seems I can now re-convert to TS and play via 
upnp if I want to.  The DVDs play on stand-alone players.

I guess I need to re-investigate Music via upnp, and perhaps look at 
mkv.  But please don't stop!
