I have a Sony Bravia KDLV4100. I currently subscribe to Cablevision and have their HD DVR box hooked up via HDMI cable. Mostly on HBO, I get a smearing effect or motion blur. It can happen in scenes where a subject is walking down the hall. Their faces look like they are smearing. I have had a tech to my house twice, telling me I'm receiving EXCELLENT signal, and have even changed out my HDMI cable and splitter. I've adjusted all settings on my TV including the Cinemotion settings but am still having the same problem. Is this just an issue with Cablevision? I am thinking about going to FIOS to see if it will solve the issue. The only problem with that I'll be hit with about 20 bucks a month in taxes on their bill. My blu-ray looks perfect as well as my XBOX 360. Are the HBO channels on Cablevision just overcompressed? Will moving to FIOS solve my problems?
Thanks!
