What server software are you using?? Ive tried both Tversity and twonky media server. Both are great, but i prefer twonky. As far as Tversity goes, there is a change in the profile.xml file of Tversity that may need to be done. I have found that 90% of the files I have do not have the correct Fourcc codes. I use avic, which is located here http://www.inmatrix.com/files/avic_download.shtml for single file four cc code changes and for batch four cc code changes, I use http://www.winremote.dk/fourccchanger.php. Hope this helps!!!
