Advertisements I have Brighthouse networks in central Florida. I recently switched from a Cisco 8640hdc to a roamio plus with tuning adapter. I've noticed that the picture quality of the roamio is not as good as the 8640, I'd say about 90%. The issue is compression, not blocky, but rather small squiggly lines around the edges of objects. I'm sure it's set to best quality for recording, and it's set to 1080p and my display en reflects this. Any ideas? I'm pretty new to TiVo.
