Cisco's record iin this sector is laughable
Look at Cisco's recently discontinued DMA2100 and DMA2200 Media Center Extenders. Despite constant pleas from users in the support forums for such simple additions as "Wake on LAN" and proper support for DivX (the device plays Xvid, and will happily play DivX if you change the fourcc header), nothing was ever forthcoming. Not so much as an acknowledgement. If it wasn't for the fact that posts critical of Cisco as a company were deleted in short order, you'd swear that nobody at the company ever read the support forums (they certainly nevr answered any questions).
If that experience is anything to go by, I wouldn't touch any "Home Entertainment" devices from Cisco with a barge pole. They might have 50% of the home networking maket, but when was the last time you heard someone saying "I wish my router could do ....". If you're not able to respond to that sort of request, stay out of the Home Entertainment market, where that sort of request will occur.
