I noticed on Sunday during football that there was a strange motion issue, almost like dropped frames or slight ghosting on CBS HD (NJ Cablevision) but no effect on audio. I also noticed the same strange effect last night during How I Met Your Mother. Anyone else notice anything like this? I am running 9.1, but don't think this is software related unless the bitrate is higher on CBS HD and is causing this, but doubful. Thoughts?
