D-Link now has available in the USA and Canada a second network media player that allows PC-based high-definition video to be enjoyed on HD TV sets.
The DSM-510 High-Definition Media Player - $240 from D-Link's online store - can connect using 802.11g/b wireless for stills, music and standard-res video but requires Ethernet cabling or fast (200Mpbs) mains-borne networking for high-def.
The Viiv-compatible newcomer is selling alongside the similarly-priced DSM-520 and, though the two feature-sets are similar, there are other difference apart from Viiv, perhaps the most significant being size.
