Sorry, forgot to mention that all the content is stored on a 1tb external HDD connected to my home pc / network. The network cable length is around 50 ft (900B to router through D-link LAN splitter). Other components (Tata sky HD+) also share the same link.
Have also checked portable HDD upto 1 tb, pen drives upto 32 gb and also connected my cell phone (N8-00) through usb. Flawless performance seen as of now.
Thanks.
Amit
