Having been exposed to the IPTV industry a little I've found that most of the vendors don't make real wonderful products. Some of them are still very beta and missing features, both set top manufacturers and middleware alike.
After playing with some pretty crummy DVRs I began to wonder why TiVo doesn't get into this market. It seems like a natural evolution of their business, plus they have the best DVR software and features available. They make attractive, well-built set tops and have great brand recognition and consumer loyalty.
It seems like they could wrap up the whole package and supply equipment and middleware to IPTV providers.
