My TiVo box is making a ticking noise similar to maybe an old DVD player or Xbox game skipping. Only had it installed on Thursday 30th June so not sure what's happening as wouldn't expect problems so soon.
Is everything running ok for you now since you have it placed on a mat? I hope this has improved things for you. If this is continuing to be an problem noise wise for you let us know and we'll be happy to help out.
