I don't know how I managed to forget mentioning Knots2 for Maemo.

http://wiki.maemo.org/Knots2

I used it a couple of times to convert on the fly some movies I had, and sent them over LAN, optimized for the N900 (but that's just one of the many options), to my phone,which I had connected to a TV-set. It worked surprisingly well.

It took a bit of configuring but the client for Maemo was really decent.

For the diablo client look here:

And look at the wiki for a server on the OS of your choice.

By the way, I noticed on the download page of ffmpeg that that are "static" builds available for armel, as well as regular debian packages for armel. You may have some luck over there.
