I have a Panasonic Blu Ray HDD recorder which is DLNA certified.
However I noticed when attempting to playback recorded programmes to another DLNA certified device (eg PS3) only TVNZ channels work.
Recorded programmes from Mediaworks or Prime etc have no audio. Video is fine.
Is this something to do with settings, or does anyone know if this is some kind of copyright/broadcast restriction from Mediaworks & Prime?

Any advice greatly appreciated!
