I had wondered when TiVo changed the pricing plan how would TiVo collect from somebody who just stopped paying (by changing their credit card). I just found out as a friend just got a TiVo and it showed account closed (what was expected) but on the TiVo web sight when you put the TSN in the red print came up saying that this unit was already activated. Calling TiVo he found out that the former owner had money that was owned TiVo Inc on this TiVo. The CSR is going to try to clear up this TiVo but is not sure how long it will take or if it can been done. This means that TiVos in the wild may have a lien on them, bad new for the used market and unlucky customers who get them. In the case of E-Bay (my friend got his at an outdoor flee market) if the seller was not the owner or the owner owes more than the unit sold for he may not want to pay TiVo. I don't know how big a problem this may become but buyers should get the TSN before paying on E-Bay.
