Thanks for the answer. I've changed the subject to make it more adequate.

Fortunately (?) the problem can be reproduced without a TV set.

I'm a complete novice, I don't change the defaults.

The files extension is mpg, the file program reports "MPEG transport

My Video directory is empty.

I've sent more detailed description to gupnp-list :

Unfortunately I got no answer (yet?), the list doesn't seem active.
