I have a Series 2 tivo, bought from them. I am having ~15 seconds of audio drop-out with accompanying violet, blue or green coloring and very mild smearing of the video. This happens approximately 15 minutes into a particular show, Burn Notice, and does not happen in any other shows. What should i do to troubleshoot? I can't imagine this is a cable problem, but i am open for anything. In the last episode, a 2 hour special, it occurred at 15 minutes and 1:04. Thanks in advance.
