First I would like to understand if it actually transcodes something (and if the CPU of my PI can do it) :D
I created a "Test" stream profile where i can play with the settings; on access entries I created an account where the streaming profile is "Test". I am using VLC as front-end to see what and how it works: i open a network stream like this: http://username:password@ipadress:9981/playlist/channels and I start the channel (always the same one, SD channel).

This one works!!! The bandwidth is strongly reduced (800kbps instead of 4000), but my CPU goes quickly to 100% :(
I will make more experiments from my XBMC, but I was wondering if i shouldn't say to VLC that I'm using H264 (I don't know actually know how/where)
