Thanks for the file information. Mezzmo server will stream this AVI file directly to your Samsung Blu-ray player when using the various Samsung BDP device profiles. So the fact that your Samsung player rejects it means that it cannot play it via DLNA (whereas it can play it via USB; we have found this is quite common that playing via USB and playing via DLNA produce different results since often hardware players have different code in their firmware for playing files via USB vs. via DLNA).

Try pre-transcoding the AVI file to another format and see if it plays. To pre-transcode the AVI file, follow this FAQ - http://forum.conceiva.com/showthread...nscoding-Files. Once pre-transcoding has completed, try streaming the video again to your Samsung BDP. Let us know how you go.
