with media player i m not able to understand how i ll get 5.1 channel output?
Anil...there are 2 ways to get 5.1 from a WDTV media player and it depends on your AVR / HT.
1. If your AVR / HT has HDMI out ::
WDTV >>>(HDMI)>>> AVR >>>(HDMI)>>>TV = This is 2 sets basically routing the content thru the AVR to process the 5.1.
2. If your AVR has a digital IN ::
WDTV >>>(HDMI)>>> TV &
WDTV>>>(Digital)>>>AVR
