I've done some debugging, mainly using an mswindows machine with a share 
that magically also showed up in the TV. There, I found the share that 
is shown on the tv in which I dumped some movies of a known format.

Start: get the file VTS_01_0.VOB from a myth-archive dvd and dump it 
there. This file is known to be mpeg2. This was a no-show.
Then I changed the extension to: mpg, mpeg, avi. As the extension was 
not shown, I also changed the name to find what name was which 
extension. It appeared 'file.mpg' worked! The movie showed!

Final test: Copy a recording from /var/lib/mythtv/recordings/. In there 
the recordings already have the mpg extention. Copied that to the share 
'et presto'. These movies, the raw recordings from the haupauge pvr show 
as they should.

Hence, my question on the myth-upnp server, what extension does it use 
in the shared recordings? Can I change that without hacking the source?
