Advertisements I am new to the TiVo community and would appreciate any help you guys could lend me. I have Comcast and for some reason the past couple of days my HD sports programs have been real choppy an makes it unwatchable. I have a few football games saved on my TiVo and when I went to watch them they were also choppy. Not choppy with pixels becoming distorted but it seems as if there is a lag of some sorts or it looks like a strobe light is going and makes the play look robotic. Just wondering if a simple reboot would fix the problem or if there may be a problem with my tuner. Thanks alot.
