This has probably been covered, but I was unable to find it. I am moving into an area that has Comcast cable, but not an area that uses the TiVo boxes for their DVR. I was planning on buying a box and renting their cable cards to put in it. Here is my question if I get two more TiVo's, but do not get cable cards for them, will I be still be able to wirelessly send shows between the boxes over my network? I realize that I will need to have wireless set up in the house and that each box will need a wireless adapter. I just hate renting more of their cards than I have too. Thanks in advance for the help.
