Ok, you were right guys! I installed MediaTomb per your recommendations, and it works like a charm! Installation and configuration was easy as a pie thanks to Gentoo's portage and MediaTomb's web UI. Moreover its DLNA is compatible with my telly! Yay! :) Streaming of video, conversion of unsupported formats and everything just works in five minutes of work! And it is much better than Twonky Media Server which is the only officially supported software by Panasonic. Thanks for all your time guys! Peter
