Prior to yesterdays's upgrade I was streaming files fine over DLNA from my NAS.

After the upgrade the BDP-S480 refuses to see the NAS, I've tried

- removing all devices from the BDP-S480 and re-scanning for servers

- downloading and applying firmware update (said it was already done)

- Re-starting NAS

- Re-starting router

- re-setting to factory settings

Streaming to my Bravia tv and PS3 work fine, from the same NAS on the same network so it's obviously a firmware issue.  Any ideas anyone?
