I have a PS3 connected wirelessly to my ASUS RN-T16.
I have configured DNLA media sharing of my HDD and both my PC and Xbox 360 can access this without problems.
For some unknown reason though, my PS3 continually gets the Protocol Error DLNA 2104 and whilst I can see the media device on my PS3, when I try and access it, nothing ever appears.
I have configured the db path to /mnt/Share/DNLA and can see by accessing this folder on my PC that there is data being wrote here (also verified by the fact my 360 and PC can access the NAS).
Any ideas what I could try to get the PS3 working? I have manually port forwarded the media server ports and set a static dhcp address on the network.
