Not long had a swap out from a V+ box to a TiVo box. I thought the V+ had a noisy clunky hard drive but this TiVo one surpasses even a V+. Even at its noisiest the V+ wasn't as bad as this. The noise from the TiVo can be heard over the TV and never stops! At least the V+ went through the odd quiet spell. Picking it up makes no difference so it not resonance - just incessant noise. Any suggestions?
