I am having no success at all . I uploaded an album in wav file to the wd play book which is a network hard drive with dlna support i believe ,and I can access and listen to it on my network with one of my computers . The marantz sees the drive . It brings up wonkey I believe it says . I can see the album and choose a song with the marantz remote but when I hit play it fails . It says file format error . I used to have a dedicated computer with my Yamaha rxv2700 but was told you can use a network drive instead . I am using a dlink router and dhcp is enabled in the marantz receiver . Any ideas guys ?
