New User. Problems

Have just downloaded and installed Serviio. Am streaming Video/Music and Images from Windows7PC to Panasonic Viera TX P65VT50 TV over a wired network
Particularly interested in streaming Home Videos shot over last 12 years, initially as AVI's converted to MPEG2 and , more recently as AVCHD shot on Panasonic HD Camcorder, edited in Adobe Premiere ans stored on hard disc as AVCHD / MPEGTS / AVC Videos
These all play quite happily on the TV when streamed using Windows Media Server but, having installed Serviio, I simply do not see any HD video files within the Folders in which they are stored. The MPEGs generated from AVI's shot on older camcorders are there and play fine. Where MPEGS and AVCHD are mixed in a folder only the MPEGS appear. This is not a question of Serviio not playing them but not even recognising or seeing them
I'm sure I have not set something up correctly or made a stupid mistake but cannot figure it out
Any help much appreciated
