We've got some experience with glitchy HDTV/DVR set top boxes, but it looks like things are even worse over on the other side of the pond. With almost all their HD customers only recently buying sets for the world cup, many are using the digital connections and experiencing a lot of problems like picture and sound dropouts. Specifically cited is the implementation of HDCP, as many have been able to get around the problems by switching to analog connectors.Of course this doesn't do much for customers expecting a sharper picture out of their digital hookup or maybe have spent a lot of money on a digital cable they can't use, but SkyHD and even some TV manufacturers may have to update their software for this to be fixed.
Glitch ridden high-def rollouts are becoming all too common, particularly for the "lucky" few who were able to get their service installed prior to the World Cup, but this may explain why some service providers are so unwilling to even enable the HDMI or DVI outputs on their boxes. If it doesn't work, there is a resulting shifting of blame between the provider and TV manufacturer while the customer's problem continues. Same problem with rolling out CableCard, neither side wants to take responsibility for making it work if there's a problem.
