The 630 is middle of the pack when it comes to reliability, features and quality. For the best PVR, go with Bell but programming is more expensive. The worst are cable company Cisco PVRs. That, of course, can change anytime a new model is released. New PVR models and those with major new features recently added tend to be very buggy. The 630 is starting to get fairly mature and stable as PVRs go. It's still needs some work to get as good as the Bell PVRs, but their basic design has been around for a lot longer than the SD 530/630 design. The entire Canadian BDU industry has a disgraceful record with their proprietary hardware. In any other market segment, these devices would be considered a joke in every respect. They only exist due to market protection.
