Advertisements I have a TivoHD with a cable card and a MyDVR expander. A few months ago my cable company, WOW, was having an issue where Tivo users were seeing a picture stuttering problem on a few HD stations. WOW looked into the issue, was able to recreate it in their labs, and fixed the problem. A few weeks after the problem was fixed, I noticed on these same channels that had the stuttering problem, I was now having a fast forwarding problem. If I used the 2x or 3x fast forward, instead of jumping back the 8 seconds or so that Tivo usually does, I would jump back over a minute. In the cases where I was fast forwarding just a short amount of time, I would sometimes jump back to the same spot I started. I contacted WOW about the problem, but they say they cannot duplicate this in their labs. I'm only seeing this on a couple HD channels. Otherwise I'm fast forwarding as usual. Does anyone know what could be causing this problem? Is it a problem with my Tivo or with the cable signal? Anything I can do to attempt to fix it? Thanks!
