Just bought three TiVo HD Units (One of the 30G and tow of the smaller ones). I am replacing my cable boxes with these units, however these uniots are much larger than my calbe boxes. I have a shelf that is 10 inches deep, but need one that's at least 14 inches deep for these boxes. Does anyone have any suggestions? Looking all over internet and found a few, but thought this would be the best place to get some ideas.
