For quite some time, our TiVo box has been messing up when watching TV (including live TV & recorded shows). It can go quiet, spaz out, make the screen all pixel-y, jump back and forth in the program etc. It's fair to say this is all pretty annoying, and the fact that rewinding, pausing & fast forwarding doesn't fix it but make it worse is very frustrating. This happens frequently and now more often than before, and we're sure it's no problem with our actual Television as when going on other TiVo features (such as Home or My Shows), the screen is fine. It can happen multiple times a day. Could anyone help?
